I.The Instrument Of Introduced

Welcome you to become a customer of HZGC-1212ADissolved Gas Analyzer of Huazheng Electric Manufacturing(Baoding) Co.,Ltd

1．1 The Working Principle Of Dissolved Gas Analyzer

Dissolved Gas Analyzeric analysis technique is an analysis of multicomponent mixture separation and analysis technology. It mainly uses the difference in boiling point and polarity of sample and in the chromatographic column adsorption coefficient, so that the various components in chromatographic column can be separated and analyzed qualitatively and quantitatively.

 A Dissolved Gas Analyzer use gas as a liquid phase (carrier gas).When the sample is fed into the injector and gasified,it will get into the packed column or capillary column with the carry of carrier gas. due to the differences in boiling point, polarity and adsorption coefficient of sample the various components in column will be separated.Then detect the components by the column after the detector according to the physical and chemical characteristics of components.Finally sent it to the chromatography workstation through the local area network (or the Internet) ,recording and analysis the components of the gas chromatogram by chromatography workstation and obtain  the components analysis report.

        Because the method has characteristics of high separation efficiency, fast speed of analysis and less consumption of sample, so it has been widely used in petroleum chemical industry, biological chemistry, medicine and health, the health and quarantine, food inspection, environmental protection, food industry, medical and clinical departments. Dissolved Gas Analyzery has solved the industrial production of intermediates and quality inspection of industrial products, scientific research, environmental testing, production control and other issues in these areas.

1．2 Characteristics Of HZGC-1212ASeries Dissolved Gas Analyzer

As we all knows, the traditional Dissolved Gas Analyzer is working with 1 chromatographs, 1 AD converters, 1 sets, 1 sets of computer printer mode. In this way the chromatograph should be equipped with more chemical factory, laboratory, colleges and universities ,the use and management of equipment is very inconvenient,the equipment should be invested duplicately and wasting seriously . Equipped with a large number of computers in the equipment management and data management also bring a lot of inconvenience to the user. At the same time, the traditional mode is often use the Dissolved Gas Analyzer of one manufacturer and workstation of another manufacturer to make the whole system.These make the function of the overall system difficult to express and the performance of the system difficult to improve.Not to speak of the function increasing raised by users (such as remote monitoring data transmission, the monitoring instrument etc.).

Aiming at the disadvantages of the traditional Dissolved Gas Analyzer, Huazheng Electric Manufacturing(Baoding) Co.,Ltd use its strong technology development strength and the brand new industrial modeling and electronic circuit, and apply the mainstream of the technology (IP Technology) to the Dissolved Gas Analyzer, then develop the new type of Dissolved Gas Analyzer. This instrument completely abandon the production of chips , disassemble the chip and RS232 serial communication which is on the out and use the latest high integration of industrial-grade chip, bussing technique, Ethernet technology, micro flow gas control technology and data processing technology, optimized the temperature program and gas control, improve the reliability of the instrument and the maintenance fundamentally .

 Due to network technology and high precision AD conversion circuit,the series of HZGC-1212ADissolved Gas Analyzer thoroughly break the work mode of existing of cumbersome bulky chromatograph and enables multiple chromatograph sharing 1 sets of computer to complete data analysis, printing, storage become a reality, and realize the remote transmission of remote monitoring and chromatographic data instrument the maximum degree, reduces the user laboratory investment and operation cost, convenient the management of real-time tracking of product quality.
