氩离子化检知器是目前色谱用的最灵敏的检知器之一,它可以检查出含10~(-11)克/毫升的物质。但用这种检知器作定量分析还存在着校正因子的问题。我们根据气态物质电离理论并考虑碰撞频率及分子电离截面等因素,提出一个计算相对克分子响应(亦即克分子校正因子)的公式。用这一公式处理我们所研究过的烃类体系的数据以及前人的结果,都证明计算值与实测值基本上是一致的。 Lovelock认为分子的电离比率只由碰撞频率决定,与分子类型无关,但他的实验结果与理论推论矛盾很多。此外,他提到电离截面检知器(属于氩离子化检知器的一种类型,只是电压较低)时,
Argon ionization detector is currently one of the most sensitive detection of chromatography, it can detect containing 10 ~ (-11) g / ml of material. However, the use of this detector for quantitative analysis there are still the problem of correction factor. Based on the theory of ionization of gaseous species and taking into account factors such as collision frequency and molecular ionization cross section, we propose a formula for calculating the relative molecular response (ie, the molecular correction factor). Using this formula to process the data of the hydrocarbon systems we studied and the results of our predecessors, we have shown that the calculated and observed values are basically consistent. Lovelock thinks that the ionization rate of a molecule depends only on the collision frequency, regardless of the type of molecule, but his experimental results contradict the theoretical inference. In addition, he mentioned ionization cross-section detector (a type of argon ionization detector, but lower voltage)
