Description

The purpose of this study is to compare alternative processing and preservation techniques. For the present discussion processing includes filtering, chilling, freezing, and the addition of acid or other chemicals to reduce or stop bacterial transformation of the constituent to be measured in the sample. Since the immediate processing and analysis of samples is rarely possible, scientists, water quality managers, and analysts must determine an appropriate alternative to immediate analysis.
