提出并建立了气相色谱-微波等离子体炬(MPT)原子发射光谱和离子化双检测器系统.以Ar气作为等离子体工作气体,O2气作为等离子体屏蔽气体,同时获得了被测组分的原子发射和离子化信息,并对不同种类有机化合物的相对响应系数及检出限进行了测定.
A double detector system in which MPT is used as the atomic emission spectrometry detector and ionization detector simultaneously for gas chromatography is developed firstly. Argon is used as the plasma gas and oxygen as the sheath gas. The relative response coefficient and the detection limit of different organic compounds are determined. The atomic emission signal and ionic signal is firstly obtained at the same time.
