Audited Supplier XHSP1700 Gas Chromatograph This chromatograph has reasonable structure design, atmospheric appearance, stable performance and convenient operation. And loaded with the large-screen color display technology independently developed by our company and the unique network remote transmission and control functions, making the instrument unattended, decentralized detection and centralized control a reality. In addition, the instrument can also be equipped with electronic flow controllers (EFC) and electronic pressure controllers (EPC) according to customer needs, and one-key operation function, which greatly improves the reproducibility of analysis results and the level of automation, shortening The gap between domestic models and imported models. The XHSP1700 power gas chromatograph adopts the three-detector process recommended by the national standard. It can complete the total content of the eight components (H2, O2, CH4, C2H2, C2H4, C2H6, CO, CO2) of the dissolved gas in the insulating oil with one sample injection. analyze. The minimum detection concentration can meet the requirements of the gas volume pair in the unit volume of oil when the injection volume is 1mL: H2≤2ppm, C2H2≤0.1ppm, CO, CO2≤2 ppm, qualitative repeatability: deviation ≤1%; quantitative repeatability :Deviation≤3
Main Function
As we all know, the traditional electric gas chromatograph works by a chromatograph, an AD converter, a set of computers and a set of printers. This way of working makes it very inconvenient for users who are equipped with more chromatographs to use and manage, and there is a serious waste of repeated investment in equipment. Aiming at the disadvantages of this traditional power gas chromatograph, Xi'an Xuzhihui Electric Co., Ltd. uses its strong technical development strength, adopts brand-new industrial models, electronic circuits, and applies today's mainstream technology (IP technology) to power gas phase.
Chromatograph, a new type of electric gas chromatograph developed. The instrument abandons the discontinued chip, disassembled chip, and the obsolete RS232 communication serial port. Instead, it adopts a new and highly integrated industrial-grade chip, bus technology, Ethernet technology, micro-flow gas control technology and data processing technology, and optimizes The temperature control program and gas path control fundamentally improve the stability and maintainability of the instrument.
★ Advanced technology 10/100M adaptive Ethernet communication interface, and built-in IP protocol stack, so that the instrument can easily realize long-distance data transmission through the enterprise's internal LAN and Internet; make the instrument unattended, decentralized detection, and centralized control Become reality;
★ Three independent connection processes are designed inside the instrument, which can be connected to local processing (lab site), unit supervisor, and superior supervisor, which can conveniently enable unit supervisor and superior supervisor to monitor the operation of the instrument and analyze data results in real time; Manufacturer, can realize remote diagnosis, remote program update, etc. (user license required);
★ The instrument is equipped with a 5.7-inch large-screen color LCD screen; The keyboard operating system has two operating systems in Chinese and English, which can be switched freely; to meet the needs of different operators;
★ The instrument adopts a multi-processor parallel working mode, which makes the performance of the instrument more stable and reliable;
★ Automatic identification technology is adopted; it has fault diagnosis and power-off data protection functions, and can automatically memorize the set parameters;
★ The instrument adopts a modular structure design, which is clear in design, easy to replace and upgrade, and protects the effectiveness of investment;
★ Brand new The microcomputer temperature control system has high temperature control accuracy, excellent reliability and anti-interference performance; it has a six-channel completely independent temperature control system, which can realize sixteen steps of program temperature rise; it has an oven automatic rear door opening system to improve the accuracy of low temperature control. The temperature rise/fall speed is faster;
★ The instrument is designed with a timing self-starting program, which can easily complete the online analysis of gas samples (online automatic sampling components are required);
★ The instrument is equipped with the domestic mainstream "transformer oil gas analysis workstation" with powerful functions and operation Concise; and can realize remote control of the chromatograph, such as modifying temperature control parameters, realizing automatic ignition, adding/breaking bridge flow, air flow control, etc.
