Use of LC/MS to cut costs and improve data quality for BRAC clean-up projects
- Quanterra Environmental Services, West Sacramento, CA (United States)
Environmental restoration of military bases affected by the Base Realignment and Closure Program (BRAC) often requires testing for explosives compounds and degradates of chemical warfare agents. Established analytical methods would require up to five separate tests in order to measure all of the common contaminants from these two classes of compounds. Furthermore, these tests use gas chromatography and liquid chromatography techniques which can be subject to severe limitations, particularly in complex environmental samples. The presence of interfering compounds often results in increased detection limits for analytes and the potential for false-positive identifications. The author has developed two liquid chromatography/mass spectrometry methods which replace up to five of the established methods. The ability to combine these test results in reduced testing costs and increased sample throughput. The use of mass spectrometry also improves data quality, allowing for measurement of most or all analytes in severely contaminated matrices with far less chance of increased detection limits or false-positive identifications. Data, including method detection limits and chromatograms from real-world samples, will be presented which demonstrates the improved data quality offered by the use of LC/MS versus established methods.
