氮磷检测器(NPD)对含氮含磷有机化合物有特征响应,其中,不同的含氮化合物在响应上又有明显差异。Kolb认为,含氮有机化合物分子在铷珠周围形成电子亲和能较大的CN基团,此基团参与检测器空间的电离反应,获取电子成CN~-,因此,产生较大的离子流,即响应。我们认为,该理论的主要特点是能定性地解释含氮化合物在此检测器上有特征响应这一 Nitrogen and phosphorus detector (NPD) has a characteristic response to nitrogen-containing phosphorus-containing organic compounds, of which different nitrogen compounds have significant differences in response. Kolb thinks that the molecules of nitrogen-containing organic compounds form a large CN group around the bead, which participates in the ionization reaction in the detector space to obtain electrons into CN ~ -, thus, a large ion current , That is, response. In our opinion, the main feature of this theory is the qualitative interpretation of the characteristic response of nitrogen-containing compounds to this detector
