Method 3513

Tetranitromethane by GC-NPD

This method is for the determination of tetranitromethane. Samples are collected with an impinger containing 15mL ethyl acetate, and then analyzed by GC with a nitrogen phosphorous detection system. The working range is 0.02 to 2.5 ppm (0.2 to 20 mg/m³) for a 100-L air sample. A flame ionization detector can be used but has less sensitivity. A Stabilwax-DB capillary column can be used as an alternate to a DB-1 capillary column. Note: This method revises and modifies S224.
