Functions and characteristics
1: using the advanced technology of 10/100M adaptive Ethernet communication interface, and the built-in IP protocol stack, the instrument can easily through the intranet and the Internet to realize remote data transmission; convenient laboratory installation, simplified laboratory configuration and convenient data management.
2: Design 3 independent connection process inside the instrument, can be connected to the local processing (Laboratory), director of the unit (such as quality inspection, production director and chief), and Supervisor (such as environmental protection bureau, bureau of technical supervision, etc.) can conveniently make the unit supervisor and the supervisor of real-time monitoring instrument operation and analysis the results of data.
3: instrument selected NetChromTM workstation can support multiple chromatograph work, realize data processing and control, simplify document management, and reduce user's laboratory investment and operation cost to the greatest extent.
4: the system has a Chinese and English operating system, and users can switch on their own according to their needs.
5: the temperature control area can be named freely by the user, which is convenient for the user to use.
6: the instrument adopts multi processor parallel operation mode, making the instrument more stable and reliable. It can meet the analysis of complex samples, and can choose a variety of high-performance detectors, such as FID, TCD, ECD and FPD, which can install four detectors at the same time. It is also possible to select and install other detectors after the purchase of the instrument by the addition of detector.
7: the instrument adopts the modular structure, the design is clear, the replacement and upgrade are convenient, and the efficiency of the investment is protected.
8: new microcomputer temperature control system, temperature control precision, reliability and anti-jamming performance; temperature control system with six completely independent, can realize the sixteen step temperature programming, analysis the equipment for a greater range of samples; with column box automatically after the door system, the temperature control precision is improved. Heating / cooling speed.
9: instrument is equipped with advanced electronic flow controller (EFC) and electronic pressure controller (EPC) to achieve digital control, which can greatly improve the reproducibility of qualitative and quantitative results.
10: the device is designed to be self starting program. It can easily complete the on-line analysis of gas samples (equipped with on-line automatic sampling components).
11: the operation system of the keyboard is controlled by the whole computer, the operation is simple and convenient, and the automatic identification technique of the detector is designed. With the function of fault diagnosis and power failure data protection, the parameters can be automatically memorize.
12: the instrument has a 24 bit AD circuit with low noise and high resolution, and has the function of base line storage and baseline deduction.
13: acquisition of chromatographic signal and data processing, suitable for WinXP, Win2000, Windows7 and other operating systems. The CDF file, which meets the standard of A/A (American Analysis Society), reads the sample data, so it can be used to track the chromatogram workstations such as Agilent and Waters.
15: the chromatographic system with complete independent intellectual property rights has the standard interface of MODBUS/TCP and can be conveniently butted with DCS.
16: the instrument can be connected with the automatic sampler produced by many manufacturers at home and abroad, such as SHIMADZU AOC-20i, HT series efficient liquid and gas automatic injector of Italy HTA company.
