三、程序升温系统上讲讲了恒温系统,对其工作原理进行了详细的讲解.它对于柱箱、检测室和进样器的恒温提供了条件,适用于很多样品的分析.但对宽沸程样品就不适用了,因为恒温方法不易分离样品中低沸点成份,表现在色谱峰分离不开,而对于高沸点成份,出峰时间长,峰又矮又宽,峰形不好,不利于数据处理.为了改善宽沸程样品的分离效果,缩短分析周期,根据样品中各组份沸点不同,使各组分在各自沸点温度下得以分离.程序升温系统就能实现宽沸
Third, the temperature program on the system talked about the thermostat system, the working principle of a detailed explanation of it for the oven, the chamber and the sampler constant temperature provided the conditions for a lot of sample analysis, but the wide boiling Process sample does not apply, because the constant temperature method is not easy to separate the sample of low-boiling components, the performance of the chromatographic peak can not be separated, and for high-boiling components, peak out time, short and wide peak, peak shape is not good, not conducive Data processing In order to improve the separation of wide boiling range samples, shorten the analysis cycle, according to the different components of the sample boiling point, so that each component at its boiling temperature to separate the program temperature system can achieve a wide boiling
