Preparing Standards for Analysis of Taste and Odor

Key Takeaways Taste and odor (T&O) events in drinking water systems can arise from a variety of sources.

Stock standards must be prepared accurately to produce precise calibration curves. Two approaches can be used to analyze samples for T&O compounds: targeted and suspect screening analyses.
