Overview
This model is designed with two relatively independent chromatographic analysis systems with thermal conductivity detectors, equipped with a complete four gas path constant flow gas path control process, and installed with four chromatographic columns. The dual TCD detectors are respectively equipped with independent injection devices and detector control systems, which can be manually and automatically/manually injected with a six way valve. Each analysis system can perform injection analysis separately, or use an injection valve to inject two systems simultaneously for analysis. Due to the independent gas path control process, the two systems can operate in parallel simultaneously, and different types of carrier gases can operate separately. The system operating parameters are set separately on the keyboard, with dual signal output and one machine for dual use.

◆Two detector signal channels can be used simultaneously or separately.
◆Analyze spectrum storage, data processing, and report printing at will.
◆It can calculate technical parameters such as calorific value, white number, and relative density of natural gas.
Performance characteristics
Injection port flow rate, chromatographic column carrier gas flow rate, detector gas flow rate, precision control
Multiple injection ports can be configured: packed column injection port (with spacer blowing, can be connected to large-diameter capillary column), splitter/Non split capillary injection port, program-controlled cold column head injection port, volatile component series connection injection port (specially equipped with sample pretreatment devices such as headspace/sweep capture/thermal desorption);
Detector Design for Industry *
The amplification plate with special ceramic treatment is stable during humid seasons, automatically ignites, and has automatic protection against hydrogen leakage, making it safe and reliable.
Precise control program temperature rise and furnace temperature, precise furnace temperature tracking design
The internal control accuracy of the furnace is less than0.01℃； The temperature difference between internal points shall not exceed 1 ℃; Rapid heating and cooling, with a programmed heating rate of 120 ℃/min; Balance time of 10 seconds; Cooling time (300 ℃ to 50 ℃) for 6 minutes; The accuracy of temperature control (with a difference of less than 0.3 ℃ from the actual temperature).
Fully imported valve configuration system
*More equipped8 valves (four-way valve, six way valve, ten way valve, and liquid injection valve optional); Automatic control and sequential operation; 0 leakage blowing technology; High speed switching solenoid valve has a long service life (1 million times, 10mS).
Separated columns oven
In a multi column chromatography system, different column operating temperatures can be set separately to achieve separation efficiency for each column;
Convenient implementation of pneumatic cutting technology
It can achieve multidimensional chromatography function to separate and analyze complex samples, and can realize the blowback function of the chromatography column to save analysis time and cycle;
