Gas chromatograph is the main tool to complete gas chromatograph analysis, and it must reflect the characteristics of simple operation to achieve the purpose of fast and accurate analysis. The operator must have good operating skills. I have drawn up the gas chromatograph based on the experience of using gas chromatograph for nearly two decades. The operating skills of the instrument are for your reference.
 
    1 heating
 
    Due to the different manufacturers and quality of gas chromatographs, the way to set the temperature is different. To set the temperature by the microcomputer setting method or the dial selection method, it is generally to directly set the number or select the appropriate set temperature value to increase the temperature. And if the knob positioning method is used, there are skills at all:
 
    1.1 Over-temperature positioning method
 
    Adjust the temperature control knob to a temperature about 30℃ lower than the operating temperature to raise the temperature of the gas chromatograph. When the temperature reaches approximately the operating temperature, set a temperature indicator and heating indicator light, and then gradually adjust the temperature control knob to a suitable position.
 
    1.2 Step by step positioning method
 
    Rotate the temperature control knob towards the heating direction by an angle, the heating starts, and the indicator light is on: when the temperature is basically stable, turn the temperature control knob in the same direction. Start to continue to heat up: adjust in this way until the constant temperature is at the working temperature.
