Overview
The GC-9280 gas chromatograph (touch screen) is a laboratory specific gas chromatograph developed by Purui Instruments with dedicated research and development. It adopts a 7-inch color touch screen control and a professional chromatograph UI operation interface design, which intuitively reflects the internal temperature values of the injection port, column temperature box, detector, and the values of each detector, as well as the running time. It has a one click cooling function, simple and intuitive operation, and convenient use. This instrument is widely used in various fields such as scientific research and education, petroleum, chemical engineering, biochemistry, food safety, medicine and health, environmental monitoring, judicial investigation, etc. The instrument has high testing accuracy, good repeatability, and is trustworthy.

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, the operating temperatures of different columns can be set separately to achieve the best separation effect 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;
