REGISTRY OF RADIOACTIVE SEALED SOURCES AND DEVICES SAFETY EVALUATION OF DEVICE NO.: NR-0658-D-104-E DATE: January 16, 2018 PAGE 2 of 3 DEVICE TYPE: Ion Mobility Spectrometer DESCRIPTION:
The Valco TGA 3000 is a gas detector capable of detecting problematic impurities in Ultra High Purity Gases in order to alert the end user of unacceptable levels of contaminants that may be detrimental to their product quality. The TGA 3000 is designed to be a standalone detector, with the core technology being Ion Mobility Spectrometry (IMS). The device may be used in many different applications where IMS technology can be used.
Depending on the application the end user will have the option to install the TGA 3000 as a singular gas detection device or in-line with another gas sampling system.
The Valco TGA 3000 IMS cell consists of an inlet end, exit port, and a drift end. The Valco TGA 3000 IMS uses an americium-241 source manufactured by NRD, LLC model A-001 source assembly.
The NRD, LLC model A-001 source assembly is installed into the TGA 3000 module IMS Cell Assembly by installing the source into the thread source holder. The TGA 3000 IMS cell assembly is installed into an insulator and insulator housing, this is secured with screws and lock washers. The IMS Cell is then attached to a processor assembly which are secured by zinc plated steel and nylon threaded standoffs.
The dimensions of Valco TGA 3000 are 10.250 in. (length) x 4.75 in. (width) x 3.570 in. (height).
The expected useful life of TGA 3000 is 10 years. The TGA 3000 is labeled in accordance with 10 CFR 32.32(b). The device label is located on top of the IMS cell and the point of sale package is attached to the surface of the top plate.
Valco Instruments Company, Inc. has submitted a quality assurance and control (QA/QC) program that has been found to be acceptable by NRC for production and distribution of TGA 3000. A copy of this program is on file with the NRC.
REGISTRY OF RADIOACTIVE SEALED SOURCES AND DEVICES SAFETY EVALUATION OF DEVICE NO.: NR-0658-D-104-E DATE: January 16, 2018 PAGE 3 of 3 DEVICE TYPE: Ion Mobility Spectrometer DESCRIPTION (Cont.):
Based on our review of the information and test data provided by the manufacturer, the NRC concludes that Valco Instruments Company, Inc. TGA 3000 meets the safety criteria set forth in 10 CFR 32.30.
Therefore, the NRC concludes that the TGA 3000 is acceptable for exempt distribution.
