Non-methane total hydrocarbon portable gas chromatograph
Non-methane total hydrocarbon portable gas chromatograph Details:

GC-7990F portable gas chromatograph, portable methane and non-methane total hydrocarbon VOCs analyzer, with high integration; easy and portable; accurate measurement; simple operation and other characteristics. It complies with the national standard HJ 1012-2018 "Technical requirements and testing methods for portable monitors for total hydrocarbons, methane and non-methane total hydrocarbons in ambient air and exhaust gas."

First, collect the sample gas to be tested and enter it into the portable gas chromatograph, quantify it through the quantitative loop, and enter the chromatographic column for separation through valve switching. The total hydrocarbon, methane or characteristic factors are sequentially detected by the flame ionization detector (FID) for hydrogen detection, and multiple groups are determined respectively. Sub-concentration. Finally, the built-in processor calculates the accurate total hydrocarbon, methane, non-methane total hydrocarbon and characteristic factor values.

Miniaturized dedicated FID detector, meets 107 dynamic linear range, supports automatic ignition, automatic judgment and automatic flameout protection

Integrate the traditional online monitoring system of methane and non-methane total hydrocarbons into the same portable case, including display, FID detector, switching valve, chromatographic column, electronic flow controller, battery, gas cylinder, etc.

There is no need to connect the mains or external gas circuit to the site, and the result can be measured by one-key power-on

In order to ensure the stable use of the instrument, the host and the heat tracing pipeline are powered by independent portable power supplies.

Carrier gas, hydrogen, combustion-supporting gas and other gas circuits require fully automatic electronic flow module (EPC) control. Carrier gas pressure control accuracy reaches 0.001psi

The analyzer adopts a large color touch screen, which can display test concentration, test spectrum and instrument parameter status. The analytical instrument can be connected to a mobile handheld terminal through a stable wireless connection, and supports the control of the App on the handheld terminal

Whole process high temperature heat tracing: The whole process from sampling to FID detector adopts 120℃ to 200℃ high temperature heat tracing, which effectively solves the problem of sample condensation loss under high temperature and high humidity gas occasions and provides more accurate test results
