GC-9860 Trace Hydrocarbon Chromatograph Automatic Gas Chromatography Analyzer

GC-9860 Trace Hydrocarbon Chromatograph Automatic Gas Chromatography Analyzer

Air separation is currently the main method for industrial production of oxygen, nitrogen, and argon. Due to air pollution, hydrocarbons contained in the raw air enter the oxygen concentrator system, directly threatening safety production. The situation is quite serious Serious. In recent years, there have been hundreds or thousands of explosions in large, medium, and small air separation equipment both domestically and internationally due to excessive hydrocarbon content, resulting in astonishing direct and indirect losses. If detected at any time, the content of hydrocarbons can be predicted in advance, and measures can be taken early to prevent explosions.GC-9860The type of trace hydrocarbon analyzer can help you detect and predict in advance at any time, making it the choice for explosion-proof air separationOh

　　 GC-9860The Type III trace hydrocarbon chromatograph is an automatic gas chromatograph that can continuously and automatically analyze trace hydrocarbons in liquid oxygen, liquid air, and suction air in air separation processes, and monitor explosive components C in real-timeThe changes in the content of 1-C4 provide important reference data for the safe operation of the main condenser in air separation equipment. It can also be used as a process controller for detecting hydrocarbons in industries such as petrochemicals, steel, and gas.

　　GC-9860Advantages of a type of trace hydrocarbon chromatograph: The pipeline extending from the air separation tower is connected to the instrument, and the instrument is controlled by a microcontroller automated program to drive an automatic six way valve for sampling and injection. As long as the analysis conditions and program settings are set, it can automatically detect hydrocarbons in liquid oxygen without human supervision. The experimental results are automatically printed out and the experimenters can directly take the experimental report.

Functions and characteristics of GC-9860 trace hydrocarbon chromatograph:

Method for making calibration curve for hydrogen sulfide analysis in natural gas:

Turn on the gas, turn on the machine, wait for the instrument to be ready, aboutAfter 10 minutes, ignite and wait for the baseline to stabilize.

Connect the standard gas cylinder directly to the inlet of the six way valve through a stainless steel tube, and the outlet of the six way valve is led out through a gas pipeline and connected to a beaker filled with water to absorb excessH2S。

Put four sets of low concentration standard gases into the chromatography separately, repeat each sample three times, calculate the average value through software, and then use software to calculate the standard curve
