On-line Gas Chromatograph

GCA1000On-line Gas Chromatograph

Instrument features:

GCA1000 online chromatographic analyzer is an analyzer designed for measuring and analyzing non methane total hydrocarbons below 100PPm and acetylene concentrations below 10PPm. It provides7U chassis configuration, other configurations can be made according to actual needs. This instrument has a separation and measurement system based on conventional chromatography, providing flexible operating software, automatic calibration, and measurement functions. In addition, it also has the following characteristics:

• 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℃；
• 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；
• 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；
• 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 the atmospheric pressure, to ensure the accuracy and stability of the injection volume;
• The instrument can customize the configuration system according to the user's analysis needs, including temperature, chromatographic column, detector, etc；
• Configure EPC pressure control unit, * using electronic closed-loop control, responsible for constant pressure control of gas paths such as carrier gas 1 (acetylene column), carrier gas 2 (pre column+acetylene column), carrier gas 3 (total hydrocarbons), hydrogen and air, etc. The pressure control accuracy can be better than±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 methodspipePerforming volumetric sampling with high accuracy, low maintenance, and long service life；
• 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 shutdown and automatic heating stop, and these functions can be flexibly configured in the analysis software；
• 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;
• Automatic calibration function, capable of flexible automatic calibration and quality control points；
• Equipped with relay alarm output and 4-20mA signal remote transmission function, it is easy to interface with the user's DCS system.
