Chemical Analysis of Explosives
ALS Environmental provides a comprehensive approach to explosives analysis. ALS Environmental chemists use the following technologies and procedures to enhance our low-level explosives analysis:
Solid Phase Extraction (SPE)
Solid Phase Extraction technology allows for extremely efficient extractions, consistently achieving early 100% recoveries for all analytes. This is a marked improvement over the salting-out liquid-liquid extraction proposed in EPA Method 8330. SPE technology also allows the analyst to process samples using minimal solvent, in keeping with current waste minimization programs.
Diode Array Detector (DAD)
Diode Array Detector technology allows the analyst to enhance overall data quality by performing peak purity analysis and acquisition of UV spectra for spectral confirmation.
Second Column/Detector Confirmation
Second Column/Detector Confirmation is required by EPA methods. ALS Environmental employs CN column
confirmation supplemented by GC/MS for confirmation of detections above the MRL.
EPA Method 8330 - Method Detection Limits (MDLs)
|Analytes||Soil (mg/Kg)||Water (μg/L)||Tissue (mg/Kg)|
|ALS Environmental SOP* HPLC Method Detection Limits (MDLs)|
|EPA Method 8330M Method Detection Limits (MDLs)|
|EPA Method 8332 Method Detection Limits (MDLs)|
