气相色谱仪

打开气相色谱仪所需载气气源开关，稳压阀调至0.3~0.5 Mpa，看柱前压力表有压力显示，方可开主机电源，调节气体流量至实验要求；

在气相色谱仪主机控制面板上设定检测器温度、汽化室温度、柱箱温度，被测物各组分沸点范围较宽时，还需设定程序升温速率，确认无误后保存参数，开始升温；

打开气相色谱仪氢气发生器和纯净空气泵的阀门，氢气压力调至0.3~0.4Mpa，空气压力调至0.3~0.5Mpa，在主机气体流量控制面板上调节气体流量至实验要求；当气相色谱仪检测器温度大于100℃时，按《点火》按钮点火，并检查点火是否成功，点火成功后，待基线走稳，即可进样。

Gas chromatograph

Open the gas chromatograph required carrier gas source switch,the pressure regulator valve is adjusted to 0.3~0.5Mpa,see the pressure gauge in front of the column presure display ,can open the host power supply,adjust the gas flow

Quantity to the experimental requirements;

Set the detector temperature,vaporization chamber temperature and cloumn box temperature on the control panel of the gas chromatograph host.When the boiling point range of each component of the measured object is wide,it is also necessary to set the program heating rate,save the parameters after confiming that it is correct,ａnd begin to heat up;

Open the valve of the gs chromatograph hydogen generator and pure air pump,the hydrogen pressure is adjusted to 0.3~0.4Mpa,the air pressure is adjusted to 0.3~0.3Mpa,ａnd the gas flow is adjusted to the experimental requirements on the gas flow control panel of the host;When the temperature of the gas chromatograph detector is greater than 100℃,press the "ignition"button to ignite,ａnd check whether the ignition is successful,after the ignition is successful,the baseline is stable,the sample can be injected.
