选择性检测 meaning in English
selective detection
Examples
- Test method for sulfur compounds in light petroleum liquids by gas chromatography and sulfur selective detection
用气相色谱法和硫化选择性检测法测定轻质石油液体中硫化物的试验方法 - Standard test method for determination of trace thiophene in refined benzene by gas chromatography and sulfur selective detection
用气相色谱法和硫的选择性检测测定精炼苯中痕量噻吩的标准试验方法 - Ultraviolet absorption detector , photodiode array detector ( dad ) , fluorescence detector , and electrochemical detector are optional detectors , response value of which is relative to not only quality of the object under test , but also structure of the compound ; refractive index detector and evaporative light - scattering detector are universal detector , responding to structure of all compounds ; evaporative light - scattering detector is quality - type detector , whose responding value only relates to quality of the object under test for compounds with similiar structures ; photodiode array detector ( dad ) can , at the same time , record absorption spectra of the object under test in a prescribed wave scope , consequently , it can be used in spectrum control and inspection of purity of chromatographic peaks of the object under test
紫外、二极管阵列、荧光、电化学检测器为选择性检测器，其响应值不仅与待测物的质量有关，还与化合物的结构有关；示差折光检测器和蒸发光散射检测器为通用型检测器，对所有的化合物结构均有响应；蒸发光散射检测器属质量型检测器，对结构类似的化合物，其响应值几乎仅与待测物的质量有关；二极管阵列检测器可以同时记录待测物在规定波长范围内的吸收光谱，故可用于待测物的光谱管制和色谱峰纯度的检查。
