1. Turn on the three gas sources of carrier gas, hydrogen and air in sequence, adjust the output pressure of the three gas sources to normal values (carrier gas 0.4Mpa, hydrogen 0.3Mpa, air 0.4Mpa), ventilate for about ten minutes, and turn on the chromatograph host Under the default intelligent control state, the chromatographic workstation automatically completes the self-checking of the working condition parameters, and the control instrument automatically completes the operations of heating, ignition, and adding bridge flow until it prompts to enter the "analysis state"
2. Make a template: Use a 1ml quantitative card to take the inlet phase of the calibration gas and get the map. After processing the map, fill in the calibration gas concentration in the corresponding table, use the normalization method to get the correction factor, after the factor is obtained, change to the oscillation method and save As a template.
3. Oil sample treatment: Use a 100ml glass syringe to take 40ml oil sample, pinch the rubber cap to seal, and exhaust the air. Use a 5ml glass syringe to take 5ml of nitrogen gas, seal it with a rubber cap and insert a two-way needle, inject 5ml of nitrogen into the oil sample of a 100ml glass syringe, put the oil sample into the shaker, keep the temperature at 50 degrees, oscillate for 20 minutes, and stand still for 10 minutes Then take it out, use a 5ml glass syringe to draw out the gas, read the volume of the outgassed and record it.
4. Oil sample measurement: Use a 1ml quantitative card to extract 1ml of oil and gas, enter it into the chromatograph and click start. After the map is obtained, import the template, process the map, fill in the volume of the extracted gas, temperature, and oil sample volume and calculate the result to obtain the oil and gas concentration.
