GC-9850 Portable Automatic Gas Analysis Gas Chromatography Instrument (Gas Analysis System) Introduction to Automatic Gas Analysis Chromatography Instrument:

Gas is a combustible mixture gas, and its composition is an important parameter that affects the quality of the gas. Therefore, it is necessary for us to analyze the composition of the gas, so as to obtain the volume percentages of various components in the combustible mixture, and then calculate the calorific value and density of the gas, and analyze the quality of the gas

GC-9850Fully automatic portable gas analysis gas chromatographThrough automatic sampling, automatic injection, automatic data acquisition, and automatic valve cutting, a single injection solves the full analysis of gases such as hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, alkanes, and olefins. This instrument can achieve online detection by laying pipelines to pump the measured gas from the suction pump to the gas chromatograph for detection. The detection results are automatically processed by the analysis software, and the entire process is controlled by a microcomputer. When multiple detections are needed, the microcomputer automatically cycles according to the user's set detection sequence and number of detections, without manual intervention. It can continuously perform online detection and analysis 24 hours a day. This instrument reduces the workload of analysts and improves work efficiency; Provide reliable data for gas recycling and safe production of gas. All analyzed data can be retained for staff to reuse. Application scope of automatic gas analyzer: Used for the detection of various gases such as blast furnace gas, converter gas, coke oven gas, generator gas, water gas, calcium carbide furnace exhaust gas, natural gas, etc. In the new energy industry, it is used for the determination of gas content in various combustion tests in laboratories such as biological fermentation and biological cracking. Execution standard for automatic gas analysis chromatograph: GB/T 10410-2008 Gas chromatographic analysis method for constant components of artificial gas, coke oven gas, semi water gas, blast furnace gas, gas generator gas, and liquefied petroleum gas GB/T 12208-2008 Determination method for components and impurity content of artificial gas Automatic gas analysis chromatograph Performance characteristics: ◆ Based on the new generation of high-performance and high stability GC-9850 gas chromatograph, the operation is reliable and stable; One injection solves the complete analysis of gases such as hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, alkanes, olefins, etc; Adding a FID detector can simultaneously detect the content of benzene, toluene, and xylene in coal gas. Using the application of central cutting technology, reverse blowing technology, multi column parallel series technology, and multi detector parallel series technology, full component analysis is carried out on coal gas, natural gas, liquefied gas, as well as raw gas and process gas in chemical production processes. Injection method: The ten way valve divides the injection into two paths, one using hydrogen as the carrier gas and the other using nitrogen or argon as the carrier gas. The six way valve cutting technology ensures that CO2 does not flow into the molecular sieve chromatography column, avoiding CO2 poisoning of the molecular sieve chromatography column; Detector: Choose one or two (TCD) detectors, and if other hydrocarbon compounds need to be analyzed, an FID detector can be added. Installing a flame photometric detector can analyze sulfur-containing compounds in coal gas. ◆ Equipped with a 4/8 liter aluminum bottle containing multi-component standard mixed gas; ◆ Dual channel chromatography workstation, supporting Windows XP operating system, allows for free storage, data processing, and report printing of chromatographic analysis spectra; ◆ Can be equipped with a natural gas analysis chromatography workstation, which can calculate technical parameters such as natural gas calorific value, white number, relative density, compressibility factor, etc; ◆ It can achieve online automatic analysis, and through the installation of pipeline instruments, it can automatically sample on a periodic basis. It can monitor and calibrate the process sample gas continuously without the need for manual calibration. The probe of the pipeline can be manually sampled and tested in places where it has not been laid, which is flexible and reliable. Instrument technical specifications: 1.
