摘要: Solid phase extraction with commercial C-18 cartridges has been applied to the analysis of some well known chemical warfare agents in water samples. Different sample pretreatment and cartridge conditioning procedures, different solvents were tested study optimum conditions for efficient recovery compounds interest. The eluates analyzed a two-channel gas chromatograph equipped an autosampler retention index monitoring system. The suitability this technique real samples is discussed: rapid hydrolysis many studied poor recoveries polar degradation products are practical limitations method.
