5.3 Discrete and Composite Overview

5.3.1 Discrete Sampling

Discrete sampling is sampling wherein samples are taken into more than one
container. Inside of the refrigerator (or cooling chamber on portable sampler
units) is a stepper assembly which revolves 360° and delivers samples into
separate containers, ranging from 2 to 24 bottles. Discrete sampling is
beneficial in situations where change over time needs to be measured, such as
measuring different water characteristics over 24 hours. Labs and monitoring
personnel tend to rely on discrete portable sampling.
