Determination of phosphine exposure from zinc or aluminum phosphide fumigants continues to be a routine analytical requirement in veterinary forensic toxicology. There is a need for a more reliable and specific method than simple gas chromatography/mass spectrometry (GC/MS) analysis of sample solvent extracts, as GC/MS of extracts on capillary columns used for general screens involves significant interference from air peaks.

顶空气相色谱/串联质谱联用多反应监测技术检测兽药中的磷化氢

在兽医法医毒理学中，确定从锌或磷化铝熏蒸剂中暴露的磷化氢仍是常规分析要求。与简单的气相色谱/质谱分析（GC / MS）分析样品溶剂萃取物相比，需要一种更可靠，更具体的方法，因为用于一般筛选的毛细管柱萃取物的GC / MS涉及到空气峰的明显干扰。
