The weight loss is less than 4% of the previous weight OR 0.5 mg, whichever is less.
9.3 Calculation of Total Suspended Solids (TSS)
(A -B) x 1000 mg total suspended solids / L =
sample volume, mL Where:
A = weight of filter paper + dried residue, mg.
B = weight of filter paper, mg.
Example: A prepared filter disk had a tare weight of 0.4232 g, or 423.2 mg.
One liter of sample was filtered through the filter disk (in less than 10 minutes), and the final stable weight was 0.4267 g, or 426.7 mg. What is the Total Suspended Solids concentration?
Answer: A=425.7 mg, B=423.2 mg, Sample volume = 1 L = 1000 ml, so; mg total suspended solids (A - B) x 1000 L
sample volume, mL (426.7 - 423.2) x 1000 3.5 x 1000 _ 3.5 mg 1000 1000 L
