天然甲烷与全氘甲烷同位素的色谱分离

Isotope Separation of Deuterated Methane and Natural Methane by Gas Chromatography

摘要: 采用四极质谱仪在线测定了CD4和CH4同位素色谱总分离度(K1)与色谱条件、进样量之间的关系。结果表明，K1受色谱柱填料、长径比和样品量影响较大，载气流速影响不明显，柱温的影响与色谱柱的填料有关。

Abstract: The total separating size(K1) of CD4 and CH4 was detected by quadrupole mass spectrometer on line, and the relation of K1 and vary chromatographic conditions and sample volume were tested. The results show that the chromatographic column packing, column length and sample volume affect K1 greatly, but the carrier-gas flow not evidently.
