GC-2020B Liquefied Gas Analyzer Integrated Machine Installation and Use Tutorial

1、 Instrument installation

① Place the instrument on a stable workbench and prepare 1000ml of Wahaha purified water

② Pour potassium hydroxide into a glass and add 500ml of Wahaha purified water. Stir and melt the mixture before pouring it into the water inlet above the instrument. Observe the liquid level on the left side of the instrument and continue adding water to the middle position. After 10 minutes, turn on the instrument power and the pressure in the upper left will automatically rise to 0.3Mpa. Observe if the flow rate display is zero. The pressure gauge in the lower right corner of the instrument will rise to 0.1Mpa. After the instrument is installed and stabilized for 30 minutes, prepare for sampling and analysis

2、 Sample analysis

When taking liquefied gas, be careful to empty the air in the sampling bag (to prevent analysis errors caused by air entering), and then replace the sample three times repeatedly. After taking, immediately clamp it with a spring clip. When injecting, align the outlet of the sampling bag with the sample inlet on the instrument, remove the spring clip, and adjust the injection valve to the sampling position. Squeeze the sampling bag by hand for about 20 seconds, then rotate the valve to the analysis position. The computer will automatically collect data and wait for the sample to peak.

When taking liquid phase, the sampling bag needs to be heated to allow the gas to fully vaporize before injection!

3、 Precautions

During the use of the instrument, the liquid level should be observed in a timely manner. If it is lower than the lower scale, water should be added in a timely manner.

Please contact the manufacturer for installation guidance before turning on the instrument
