Gas Chromatography Petroleum Analysis

Network gas chromatography petroleum analysis is a special gas chromatograph for power system designed and manufactured according to the flow of gas chromatograph recommended in international standards.

The machine adopts three detector flow, one injection, two columns parallel, one shunt. The sensitivity, separation degree and quantitative accuracy of chromatographic peak are better than those of national standard and line standard.with the main advantages of most superior performance, the most simple operation and the most sensitive detection It is widely used in transformer factory, CT PT factory,high voltage electric porcelain factory, high voltage cashing factory and other power plant field .

★ The advanced 10/100 M adaptive Ethernet communication interface and built-in IP protocol stack are adopted so that the instrument can easily realize the long-distance data transmission through the internal LAN of the enterprise and the Internet, which facilitates the erection of the laboratory, simplifies the configuration of the laboratory and facilitates the management of the analytical data

★The internal design of the instrument consists of three independent connection processes, which can be connected to the local processing (laboratory site), the unit supervisor, and the superior supervisor, which can easily enable the unit supervisor and the superior supervisor to monitor the operation of the instrument in real time and analyze the data results

★ The network workstation equipped with the instrument can support the work of multiple chromatograph (253 sets) at the same time, realize data processing and reverse control, simplify document management, and minimize the laboratory investment and operating cost of users

★ The instrument can be connected to the manufacturer through the Internet to realize remote diagnosis, remote program update and so on (need user permission)

★ The instrument is equipped with 5.7-inch color LCD screen to meet different user needs

★ The system has 2 operating systems in Chinese and English, which can be switched freely

★ A multi-processor parallel operation method is adopted to make the instrument more stable and reliable, which can satisfy the complex sample analysis, and can be selected with a variety of high performance detectors, such as FID、TCD, can install up to three detectors at the same time
★ The instrument adopts the modular structure design, the design is clear, the replacement upgrade is convenient, has protected the investment validity

★ A new microcomputer temperature control system with high temperature control precision, high reliability and excellent anti-interference performance. It has six completely independent temperature control systems, which can realize the 16th order temperature programmed, and make the equipment competent for sample analysis in a wider range. With automatic back door system, the low temperature control accuracy is improved and the rising / cooling speed is faster

★ Instrument design timing self-starting program, can easily complete the on-line analysis of gas samples (need to be equipped with on-line automatic components)

★ It has the functions of fault diagnosis and power off data protection, and can automatically memorize and set parameters

★ Chromatograph built-in low noise, high resolution 24-bit AD circuit, with baseline storage, baseline deduction function

★ The instrument is equipped with domestic mainstream "transformer oil and gas body analysis workstation ", which has powerful function and simple operation

The transformer oil chromatograph is composed of sampler, detector, column box, nickel converter, gas flow control system, circuit control and detection system and network workstation
