Fig. 8From: Identification of acidic degradation products of chemical warfare agents by methylation with trimethylsilyldiazomethane and gas chromatography–mass spectrometryTICs of GC–MS analysis of water samples of the 32nd (A) and 34th (B) OPCW PTs. TMSDAM was used for methylation and a DB-5 ms column for analysis. The methyl derivatives of isobutyl ethylphosphonic acid (IBEPA), DEAESA (both spiked with 10 µg/ml) and PMPA (7 µg/ml) could be detectedBack to article page
