Determination method for nitromethane in workplace air.
OBJECTIVES The purpose of this research was to develop a determination method for nitromethane (NM) in workplace air for risk assessment. METHODS A suitable sampler and appropriate desorption condition were selected by a recovery test in which a spiked sampler was used. The characteristics of the proposed method, such as recovery, detection limit, and reproducibility, and the storage stabilit...
