APPLICABILITY: The working range is 0.02 to 2.5 ppm (0.2 to 20 mg/m 3) 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 co lumn [2].
INTERFERENCES: Any nitrogen or phosphorus compound with a similar retention time as tetranitromethane.
OTHER METHODS: This method revises and modifies S224 [1].
