How is the quality of a purifiable sump sample assessed?

The quality of a purifiable sump sample is best assessed through chemical analysis. This process involves identifying and quantifying the various substances present in the sample, which provides an objective measurement of its quality. Chemical analysis can detect contaminants, impurities, and the overall composition of the fluid, which are critical factors in determining its suitability for further processing or use.

Visual inspection might offer some immediate insights about the sample's appearance but lacks the precision required to assess the quality adequately. Temperature measurement, while important in understanding certain physical properties of fluids, does not provide comprehensive information regarding contamination or purity. Time-based observation may track changes over time but does not yield specific data about the current quality of the sample. In contrast, chemical analysis delivers concrete evidence needed to evaluate and ensure the quality of the sump sample.
