DILEMMA:
Traditional Approach
Samples are field screened on a handheld PID or OVA meter to define total volatiles in a sample.
Traditional Shortcomings ...
- Low sensitivity (PPM).
- Results do not specify each specific contaminant. (OVA measures full range of all volatile substances but cannot distinguish or quantify each contaminant of concern)
- Many substances are not detected on a PID-type meter.
Geo Lab's SRI GC is equipped with dual FID/PID detectors
- Delineate contaminant plumes in the field 'Real Time'.
- Proper well placement within the first mob to the site.
- Each contaminant identified and quantified quickly.
- Site scope based on continuous data rather than a grid approach.
Results...
Actual Chromatogram
- Analyte Specific Results: 15 to 30 chromatograms are printed on-site each day.
- High Detection Limit: 2 ppb for water, 10 ppb for soil.
- Report Included: Summary result sheet and chromatograms.
SRI Gas Chromatograph equipped with:
SRI Gas ChromatographRead up on Benzene
- Both FID and PID detectors to ensure the individual quantification of most volatiles.
- An auto-sampling device to allow for multiple unattended sample runs.
- Peaksimple software that provides high quality printouts that both qualify and quantify the contaminants.
