Types of containers and times of sample conservation

The samples represent the environment they were taken from only after a specific period of time passes, then the analysis must be conducted. That is the “time of sample conservation”. For some analyses, such as those that include extraction using an organic solvent, there might be a time of sample conservation after which the extraction must initiate, as well as the time of conservation after the extraction, only when that period passes can the analysis of the sample begin. All the samples must be stored in an appropriate container and appropriately conserved.

*The following table shows the appropriate container, conservation conditions and times of sample conservation for each of the analyses we conduct.*

a If a sample of water contains free chlorine, sodium thiosulfate is used to remove chlorine

b V-water, PV-drinking water; Z-soil or sediments; OHO-dangerous chemical waste

c P-polyethylene bottle, S-glass bottles
