Abstract: A gas monitoring apparatus capable of real-time detection of a kind of chemical warfare agent, namely diphenylcyanoarsine (DC) and/or diphenylchloroarsine (DA). Atmospheric pressure chemical ionization mass spectrometry is carried out in the positive ionization mode, the total amount of DC and DA is determined from the intensity of an ion common to DC and DA, the DC concentration is determined from the intensity of an ion specific to DC, and the difference between them is regarded as the DA concentration.

Abstract translation: 一种能够实时检测一种化学战剂（即二苯基氰胺（DC））和/或二苯氯胂（DA）的气体监测装置。 大气压化学电离质谱在正电离模式下进行，DC和DA的总量由DC和DA共同的离子强度确定，DC浓度由特定于DC的离子的强度确定 ，它们之间的差异被认为是DA浓度。
