LC/MS AnalysesMethod Challenge

Screening Requires reproducible

identification by MS or

MS/MS

Discovery Requires existing MS

and MSN databases

Exploration Requires component

detection

Absolute Quantitation Requires calibration

• Over 2790 individual wild fires

• Weather conditions:

– 3 years of below normal rainfall

– Lightning

• Poor air quality

Summary

• More work to be done, more representative samples

• Measuring contaminant free form may likely be insufficient (reference)
