SP-2305型气相色谱仪分析沸点在200℃以下的组分时,出峰正常,但当组分沸点在200℃以上时,无论使用哪种检测器,均出现不规则的平头峰,给定性定量带来困难。原因:由于该仪器柱恒温箱与检测器恒温箱相隔间隙较大,致使两箱间的载气流程管道处在室温状态,再加上柱恒温箱搅拌马达的边风从缝隙中透出,故这段管道相对于箱内的管道来说是 SP-2305 gas chromatograph analysis of components below 200 ℃, the peak was normal, but when the component boiling point above 200 ℃, regardless of which detector are used, there are irregular peak, given Quantitative brings difficulties. Reason: As the instrument column incubator and detector incubator gap between the larger, resulting in two boxes of carrier gas flow pipe at room temperature, coupled with the column incubator stirring motor wind from the gap in the open, so This pipe is relative to the pipe in the tank
