Portable Transformer Oil Gas Chromatography Machine

The Working Principle Of Gas Chromatograph

Gas chromatographic 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 gas chromatograph 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. The working principle diagram is shown below:

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. Gas chromatography 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 Gas Chromatograph

As we all knows, the traditional gas chromatograph 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 gas chromatograph 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.).

Addressing the limitations of traditional gas chromatographs, Huazheng Electric Manufacturing (Baoding) Co., Ltd. has leveraged its strong technical development capabilities to create a new-generation gas chromatograph. By integrating brand-new industrial modeling, advanced electronic circuitry, and mainstream IP technology, this instrument represents a fundamental advancement in chromatographic analysis.

The HZGC-1212A completely abandons the use of discrete chips, chip-level disassembly, and external RS232 serial communication. Instead, it employs the latest high-integration industrial-grade chips, bus technology, Ethernet communication, micro-flow gas control, and advanced data processing. These innovations optimize temperature programming and gas control, fundamentally improving instrument reliability and ease of maintenance.

Networked Operation and Remote Capabilities

Through the integration of network technology and high-precision AD conversion circuits, the HZGC-1212A series breaks away from the traditional bulky, cumbersome chromatograph workflow. It enables multiple chromatographs to share a single computer for data analysis, printing, and storage. Remote monitoring and real-time transmission of chromatographic data are now achievable, significantly reducing laboratory investment and operational costs while facilitating real-time product quality tracking.
