FREQUENTLY ASKED QUESTIONS

 

Q:

What preservative and container should I use when submitting a sample for chemical analysis?

A:

It depends upon the analytical method and type of sample collected. Specific preservatives and containers are used to maintain the integrity of samples. Please refer to the following tables to determine the applicable preservatives, containers, and holding times for a variety of analyses.

Q:

What is holding time? How does this affect the analysis that I requested?

A:

Holding time is the length of time a sample can be stored after collection and prior to analysis without significant effect on the analytical results. Holding time varies with the analyte, sample matrix and analytical methodology used to quantify the analytes concentration. For some analytes, holding times can be extended if preservation techniques are employed to reduce biodegradation, volatilization, oxidation, sorption, precipitation, and other physical and chemical processes.
