Gas Chromatography Detector Cell DESCRIPTION:
The nickel-63 foil is secured between the stainless steel cathode and the boron I
nitride electrode spacer within the outer stainless steel body.
The outer stainless steel cell body has a minimum wall thickness of about 1/16".
The l
assembly is secured by a stainless steel retaining nut which threads into one end of the cell body *, The outer dimensions of the cylindrical cell are approximately 1" in diameter and 1-3/8" in length.
The cell assembly is placed in an aluminum heat-sink block and secu, red by four blind rivets.
The rivets would have to be drilled out to remove the cell and get to the foil.
The cell heat-sink assembly is approximately 2-3/8" x 2-3/8" x 1-1/a".
Insulation is wrapp'ed around the assembly which is then covered by a thin metal outer container.
Each cell assembly is equipped with a temperature control that is not adjustable outside the cell heat-sink assembly. The control is factory set for a temperature of 360*C. The heating circuit is also balanced with the heat load so as to allow a maximum sir.k temperature of 360*C.
i LABELING:
The cell heat-sink assembly is labeled as described in 20.203(f)(1) and (f)(4);
and, in addition, the gas chromatography cabinet that houses the cell heat-sink assembly is labeled as described in 20.203(e)(1). The manufacturer has not requested an exemption from the color requirements of 20.203(a)(1).
LIMITATIONS AND/OR OTHER CONSIDERATIONS OF USE:
Since the heater and temperature control units can be removed from the assembly, the license should be conditioned to prohibit operation above 360*C.
l A manual is furnished covering cleaning of the nickel-63 foil within the cell.
temperature limitations of the cell, and general handling precautions for the cell.
I The Hewlett-Packard Company has informed the Atomic Energy Commission that it will use the Nuclear Radiation Developments N-1002 foil in place of the USRC LAB-78t.

Gas Chromatography Detector Cell 1
_ DESCRIPTION:
The electron capture detector cell is intended for use in the Hewlett-Packard Model i
5800 series of gas chronatoorsphs.
i The radioactive material is electro-plated (0.5 inch wide band) inside the iower block assembly's cavity which is 0.50 inches in dianeter by 0.75 inches in length.
The lower block assembly's (No. 18713-80020) dimensions are 1.5 inches in diameter (largest dimension) by approximately 2 inches in length and is built out of Type 303 stainless steel.
The lower block assembly is sealed to the upper block assembly by a hollow nickel 0-ring and retainer plate.
lower block assembly's cavity, an electrical connection to this anode a heater cable leading to two cartridge heaters, two cartridge sensors anc'a ga,s exit vent.
The two blocks are attached to a comon center plate by captive nuts and then mounted onto the top of the oven of thp chromatograph by four steel screws.
g.
The detector cell assembly is equipped with a temperature controller that is setable in 1*C increments up to 370*C. However, the maximum usable temperature of the detector is 350*C since the set point of the overheat protection circuit it.
370*C + 10*C.
For example, allowing a themal runaway of the oven (670'C) and the temperature controller set at 350*C temperature controller setting, the lower block temperature reached only 340*C. As seen in the next section, very little radioactive material was released under abnormally high temperature tests conducted on the detector cell.
In addition, the oven is protected from thermal runaways by the oven temperature controller (370*C) or the optional oven temperature programmer (430'C).
Under general laboratory conditions, hot gases consisting of nitrogen or argon-5%
methane are flowed into the detector from the chromatographic column effluent at a flow rate of from 10 to 100 ml/ min. Approximately 0.1% of nonidentified organic substances are expected to be present in the gas stream.
The source is a custom plated source manufactured by Amersham /Searle or New Engla Nuclear.
L ABELING:
The detector hcusing bears a label that shows the date, model number, serial number, isotope, millicurie content, radiation symbol, the wording, " Caution, Radioactf ve Material", and "See Instruction Manual Before Doerating or Opening This Cevice". The detector cell is not labeled.

Gas Chromatography Detector Assembly
~ DESCRIPTION:
The electron capture detector is intended for use in the Hewlett-Packard Model 5800 series (model designations 58XX) of gas chromatography.
It consists of an aluminum box approximately 3" x 2.7" x 2.7" enclosing a detector cell, heaters, heat sensors, insulation and electronics. Under general laboratory conditions hot gases, consisting of nitrogen or argon-5% methane, are passed through the detector cell from the chromatograph column at a rate of from 10 to 100 ml/ min.
The radioactive material is electro-plated (0.5 inch wide band) inside the cavity of the detector cell's lower block.
The cavity is 0.50 inches in diameter by 0.75 inches in length. The lower block assembly's (Part No. 18713-80020) outer-dimensions are 1.5 inches in diameter by approximately 2 inches in length and is
.F Type 303 stainless steel.
The lower block assembl assembly (approximately 1.5 inches by 1.8 inches) y is sealed to the upper block i
by a hollow nickel 0-ring and retainer plate. The upper block assembly includes a nickel anode which protrudes into the lower block assembly's cavity, an electrical connection to this anode, a heater cable leading to two cartridge heaters, two cartridge heat sensors and a gas i
exit vent.
The two blocks are attached to a common center plate by captive nuts and then mounted onto the top of the chromatograph's column oven by four steel screws.
The detector assembly is equipped with a temperature controller that is setable in 1*C increments up to 400'C. The maximum detector temperature recommended'by the j
manufacturer is 350*C. As seen in the next section, little radioactive material was released under abnonnally high temperature tests conducted on the detector cell. The cell is protected from thermal runaways by the overheat protection circuit (370 + 10*C, factory set and not adjustable by user) and the temperature programmer (adjustable by user to 400'C, recommended maximum 350'C, tested to cut off power at 400 + 15'C).
LABELING:
The detector housing bears a label (not visible from outside of gas chromatography unit) that shows the date, model number, serial number, isotope, millicurie content, radiation symbol, the wording, " Caution, Radioactive Material", and "See Instruction Manual Before Operating or Opening This Device". The detector cell bears a serial number, but is not otherwise labeled.

CONDITIONS OF NORMAL USE:
Nickel-63 is plated onto the interior of the bottom section of an electron capture detector cell which is used in the Hewlett Packard gas chromatograph.
Under normal operating conditions the detector cell temperature is not allowed to exceed 370*C.
PROTOTYPE TESTING:
The Model 19303 detector cell was subjected to and passed an acceptable series of 1
]
tests described in Hewlett Packard letters dated September 30, 1979 and November 28, 1979.
(From data provideo the detector cell exceeds the required ANSI C32211 i
specification in ANSI N542-1?77.)
{
If all safety controls fail at one time the cell may reach temperatures of t
i
600*C-660*C depending on line voltage, air circulation..etc. Under these conditions the Hewlett Packard data shows that the loss of nickel-63 would be less than 0.5 microcuries.
In addition, wipes of external surfaces of the detector cell showed less than 0.005 microcuries of removable contamination.
EXTERNAL RADIATION LEVELS:
The external radiation levels at the surface of a fully assembled detector cell do not exceed ambient background. levels when measured with a G-M survey meter.
1 The unshielded contact dose as measured by New England Nuclear with thermoluminescent dosimeters is reported to be 354 : 19 mr/hr and the dose rate at 4.5 inches is 3 mr/hr.
QUALITY ASSURANCE AND CONTROL:
The source manufacturer (New England Nuclear or Amersham Corporation) performs a
" hot" and " cold" wipe test of the lower assembly of the electron capture detector prior to return to Hewlett Packard.
The following tests are performed by Hewlett Packard on each detector cell prior to shipment.
1.
A careful visual inspection of the plated surface using a stereo microscope.
2.
Measurement of the ionization current of the assembled detector cell.

Gas Chromatography Detector Cell CONDITIONS OF NORMAL USE:
This detector cell device is designed to produce an ionized atmosphere for quantitative or qualitative measurement of elements in gas streams.
i It is an i
integral component of a gas chromatograph and will be used in ambient laboratory cemditions.
Normally the cell temperature is not allowed to exceed 370*C, PROTOTYPE TESTING:
The Model 19312 detector cell was subjected to and passed an acceptable series of j
tests described in Hewlett Packard letter dated September 9,1980.
(Based on the i
data provided the detector cell exceeds ANSI 77C32211 Classification which is recommended for detector cells to be used in gas chromatography, r
s~
In the unlikely event that all safety controls fail at one time the cell may reach l
temperatures of 600*C-660*C depending on line voltage, air circulation, etc. Under I
these conditions the Hewlett Packard data shows that the loss'of nickel-63 would be less than 0.5 microcuries. In addition, wipes'of external surfaces of the detector cell showed less than 0.005 microcuries of removable contamination.
EX~ERNAL RADI ATION LEVELS:
G W survey meter measurements show that the external radiation levels at the surface of a fully assembled detector cell do not exceed ambient background levels.
The unshielded contact dose (with the detector cell open) as measured by New l
Encland Nuclear with thermolunminescent dosimeters is reported to be 354 :
and the dose rate at 4.5 inches is 2 mr/hr.
19 mr/hr OUALITY ASSURANCE AND CONTROL:
The source manufacturer (New England Nuclear or Amersham Corporation) performs a "hct" and " cold" wipe test of the lower assembly of the electron capture detector prior to return to Hewlett Packard, i
The following tests are performed by Hewlett Packard on each detector cell prior to shipment:
1.
A careful visual inspection of the plated surface using a stereo microscope.
2.

SUMMARY
Based on our review of the information and test data contained in references listed below, we concluded that the Hewlett Packard Model 19312 electron capture detector device can be safely used by persons not having training in radiological protection.
Furthermore, under ordinary conditions of use.the nickel-63 source contained in the Model 19312 device cannot be inadvertently removed and for either routine or emergency conditions of use and it is unlikely that any person will receive external radiation dose or dose commitments in excess of the limits specified in Section 20.101(a),10 CFR Part 20 and Section 32.24 of 10 CFR Part 32.

Electron Capture Detector DESCRIPTIO5':
The detector cell is constructed of a stainless steel upper and lower body.
The upper body contains the power feed through terminal. The lower body has the Nickel-63 plated to the inside walls.
The two parts are sealed together by four screws.
The screws require a special tool to remove them; thereby restricting disassembly of the cell. The cell is very similar to the Models 19282 and 19312.
The Model 19233 is somewhat different mechanically to suite the needs of the new series 5890 gas chromatograph and are temperature-I controlled differently. The Model 19233 has the capability of being temperature.

LABELING:
1 Each cell is stamped with the radiation symbols, the Words, " Caution-Radioactive r
Material," the isotope and activity. An aluminum plate attached to a steel
(
cable is affixed to the cell by a screw.
The plate contains the radiation symbol, the words, " Caution-Radio 6ctive Material," the isctope, activity, model number, serial number, date, the words, " Electron Capture Detector," and the manufacturer name and logo.
Additionally, the ' plate contains the labeling requirements of Section 32.51, and refers the userto an instruction manual that tells them not to open or themically clean the cell.
The metal box that covers the cell allows the aluminum label plate to stick out f'or easy viewing.
The box is also labeled with the radiation symbol and 4

Gas Chromatography Detector Cell i
DESCRIPTION:
The detector cell is intended for use in a Hewlett-Packard Model 5700A series of gas chromatography.. The radioactive material.is electroplated inside the lower block assemply's cavity which is 0.50 inches in diameter by i
0.75 inches in length. The lower block assembly's overall dimensions 1
are 1.5 inches in dameter (largest dimension) by approximately 2 inches in length and it is built out of Type 303 stainless steel. The upper block assembly is connected to the lower block assembly by tamper proof screws.
similar to the tamper proof screws used in the approved Model 19312. A l
special tool is required to disassemble the detector cell..This tool is supplied with the device. The upper block assembly includes a nickel anode which protrudes in the lower block assemply's cavity, an electrical connection to this anode, a heater cable leading to two car"idge heaters L
and two cartridge sensors and a gas exit vent. The two blocks are attached to a common center plate by captive nuts and then mounted onto the top of r
the oven of the chromatraph by four steel screws, i
Identity of the cas chromatography which are acceptable for us with the Model 18713A detector include Models Numbers 5713A, 5715A, 5733A 5736A and 5739A.
Detector cell 3 kit model 18724A may appeat and is acceptable for licensing since it consists of the Model 18713A detector and associated electronics.
Also the manufacturer reports that the Modet 18713A detector cell assembly is equipped with a temperature controller that is setable in 50 C. increments up 0
0 to 400 C.
However, the maximum usable temperature of the detector is 350 C since 0
1 the set point of the ove5 eat protection circuit is 3700C Allowing a thermal h
runaway of the oven (734 C) and the temperature controller sgt at 3500C, the 1
lower block (containing the foil) reached 386 C and at a 300 C perature controller setting, the lower block temperature reached only 34
~
C.
As seen in the next section, very little radioactive material is released under abnomal high temperature tests. conducted on the detector cell.
In addition,' the oven.
is protected from thermal. runaways by the oven temperature controller (4000C) or the optional oven temperature programer (4300).
i
. LABELING:
A metal label is secured to the detector cell body by a stainless steel rope which is attached by one of the temper proof screws.
The stainless steel rope passes through an existing opening in the detector case and the attached label is placed next to the detector.
The label contains the following infonnation in addition to the radiation symbol:
O Caution radioactive material O
This device contains 15 mil 11 curies on nickel-63.
