At what temperature is the total suspended solids test typically run in a drying oven?

The total suspended solids (TSS) test is an important procedure in wastewater treatment that measures the concentration of suspended solids in a sample. The correct temperature range for running the TSS test in a drying oven is typically between 103 to 105 degrees Celsius.

This specific temperature range is critical for the accurate determination of suspended solids because it effectively dries the sample without causing the loss of volatile solids or altering the composition of the remaining materials. When conducting the test, it's essential to ensure that the temperature is high enough to evaporate the moisture content fully, as any residual water can lead to inaccuracies in measuring the solids concentration.

Conducting the test at this temperature also adheres to established standard methods for laboratory analysis, which have been validated to produce reliable and repeatable results. Thus, operating within the specified temperature range ensures that the drying process optimally prepares the sample for accurate weighing and analysis.
