Instrument features:

• Configure ETC temperature control unit, * using electronic closed-loop control, responsible for constant temperature control of column box, sampler, detector, etc., with temperature control accuracy ofsuperior to±0.1℃；
• OptionalEPC pressure control unit, * using electronic closed-loop control, responsible for carrier gas 1 (acetylene column)backblow）Carrier Gas 2 (Ethyne Column)Sampling+Pre columnbackblow）Carrier gas 3 (total hydrocarbons)Column sampling+total hydrocarbon column blowback）Constant pressure control of gas paths such as hydrogen and air, with precision in pressure controlsuperior to±0.1kPa;
• Before leaving the factory, the soap film flowmeter was used to calibrate the flow rate in each gas path. The flow rate in each gas path can be set, and the EPC unit will automatically calculate and control the pressure in the gas path to maintain a constant flow rate；
• Using quantitative methodspipePerform volumetric sampling High degree, low maintenance, long service life；
• The use of imported fourteen way automatic switching pneumatic valve for sample injection enables automated control of injection, sampling, and blowback without the need for manual intervention；
• The stainless steel pipes and quantitative pipes inside the instrument are treated with high-temperature passivation to prevent sample adsorption and improve the repeatability and accuracy of detection；
• Gas injection adopts a three-way solenoid valve balance connection. At the moment of injection, the quantitative tube is connected to the atmosphere, so that the pressure of the sample gas in the quantitative tube is the same as that of the atmosphere, to ensure the accuracy and stability of the injection volume；
• Using a hydrogen flame ionization FID detector to detect total hydrocarbons and acetylene has the characteristics of low detection limit, high detection accuracy, and stable performance；
• When the analyzer is turned on and the analysis software is started，Equipped with automatic pressure control, temperature control, automatic ignition and other functions.Before shutting down, analyze the software when it is closed，It has functions such as automatic heating stop,And these functions can be flexibly configured in the analysis software；
• The instrument can customize the configuration system according to the user's analysis needs, including temperature, chromatographic column, detector, etc；
• Automatic calibration function, capable of flexible automatic calibration and quality control points；
• Built in industrial computer, capable of WIFI wireless networking, and equipped with a 12.1-inch large capacitive touch screen design, the screen is beautiful, simple, and easy to operate；
• Supports network and serial communication, based on standard protocols such as MODBUS RTU/UDP/TCP, facilitating user integration；
• Equipped with relay alarm output and 4-20mA signal remote transmission function, easy to interface with user DCS system；
• Test components can be customized according to customer needs.

Application scenarios:

Deep cold air separation industry.
