气相色谱仪的恒温箱是仪器的一个重要组成部分。目前恒温箱的恒温方式,常用的有二种形式。一种是强制对流,就是用电机带动风扇鼓风,将加热的热空气,经鼓风搅拌,使恒温箱空间温度均匀。另一种是主要靠箱内热空气的自然对流及热传导,达到恒温箱内温度均匀的目的。前者的优点是恒温精度高,温度梯 Gas chromatograph incubators are an important part of the instrument. Currently incubator thermostat, commonly used in two forms. One is forcibly convection, that is, driven by the motor fan blowing, the heated hot air, the wind stirring, the temperature of the incubator room temperature uniformity. The other is mainly rely on the natural convection of the hot air inside the box and heat conduction, to achieve the purpose of uniform temperature inside the oven. The former has the advantage of high temperature accuracy, temperature ladder
