Small Sample Volumes? There's a Lab For That!

A common issue to using all no-purge/passive sampling techniques is limited sample volume.  By definition the amount of sample volume available to use for any no-purge/passive sampling is restricted to the amount of water available in the screened interval.  But, is this really a bad thing?  Not necessarily. 

The good news is ESC Lab Sciences has perfected using large volume injection techniques to reduce semi-volatile sample volume requirements from 1,000 mls to 100 mls or less.  For HydraSleeve users this means that for most analysis a standard 2-inch HydraSleeve, which holds approximately 625 mls of sample volume, would provide more than enough sample volume for most contaminants.  This is also the least expensive and most popular size HydraSleeve.

When was the last time you had to give 1 liter of sample for a blood analysis at the hospital? Please click here for a great article which is right on the mark in addressing the issue of groundwater sample volume and ESC's approach to a greener analysis.

For questions about the specifics of the lab process, you may want to contact Wes Vance of This email address is being protected from spambots. You need JavaScript enabled to view it.; I am sure they would be happy to talk about this exciting project.

The use of HydraSleeves coupled with ESC's innovative analytical methods provide an unparalleled opportunity to provide a safer, more energy efficient, and environmentally friendlier groundwater sampling event, from sample collection to receiving the lab results.
