At what oven temperature is TSS analysis performed?

The analysis of Total Suspended Solids (TSS) typically requires the sample to be dried at a specific temperature to ensure accurate measurement of the solids present. The standard practice for TSS analysis involves drying the sample in an oven set at 104° C. This temperature is effective for evaporating water and allowing any constituents that would affect the analysis to be accurately quantified without destroying the sample's integrity.

Other temperatures, such as 100° C, can be too low and may not remove all moisture effectively, potentially skewing results. Temperatures like 110° C and 120° C are often too high, risking the alteration or combustion of the solids being measured, which would lead to a misrepresentation of the actual suspended solids present in the sample. Hence, 104° C is the optimal temperature for reliable and reproducible TSS analysis.
