Operation steps of liquefied gas analyzer

1、 Operation steps:

• Turn on the chromatography instrument and wait for the flow rate to drop below 100;
• Open the computer and open the N3000 online workstation
• After the temperature of the analyzer reaches 40 ℃ and stabilizes, the sample can be injected for analysis. When injecting, first turn the injection handle to the left, connect the sampling bag to the sample gas inlet, squeeze the sampling bag for about 10 seconds to allow the sample gas to enter the instrument, then turn the injection handle to the right, start sampling immediately, stop sampling after the peak is out, and see the results;
• When shutting down the sample, turn off the computer program online workstation; Finally, turn off the instrument.

TwoJudge PeakThe * peak that appears within one minute is nitrogen, followed closely by methane, ethane, propane, dimethyl ether, butane, and so on.

3、 AttentionThe water level of the hydrogen generator should be between the upper and lower limits. If the water level is low, add distilled water in a timely manner. If one-third of the color changing silicone turns pink, replace the silicone.
