Product Description
Features
1, using 10 / 100M adaptive Internet communications technology, can be composed of local area network, high communication efficiency; achieve a long-distance data transmission; 1 chromatograph can be connected to three computers; one computer can connect multiple chromatograph (up to 5000 Taiwan) and operational control.
2, complete and reliable anti-control technology, all instrument parameters can be set via the computer remotely, and spectra processing.
3, support autosampler, automatic headspace sampler, cracking and other injector injection mode, the transmission through the network to achieve the online analysis and control unattended in the true sense.
4, using the new automated flow / pressure control EPC, EFC technology, digital control parameters (flow and pressure) all gas line, the mode is divided into constant current, constant voltage, shunt three. 4-order programs can boost pressure precision 0.01KPa, traffic 0.01sccm.
5, with rapid heating and cooling structure can be realized a heating rate 80 ℃ / min; achieve working temperature environment; conditions in liquid nitrogen, to support a wide range of -80 ℃ to 450 ℃ temperature control.
6, the use of intelligent hydrogen, air, automatic control technology, electromagnetic valve automatically switches the gas, enabling automatic ignition function in the true sense.
7, has a 4-way external events, support for multi-valve switches to achieve a multidimensional chromatography systems.
8, advanced gas flow path can be achieved and a hydrogen flame detector, while the thermal conductivity detector, can also be dual thermal conductivity detector simultaneously.
9, using the world's latest digital integrated circuit devices and technologies that enable high-precision instrument control (temperature up to 0.1 ℃), its stability and reliability performance can be comparable with the imported equipment.
10, advanced dual function automatically opened the door, the door switch can automatically adjust the angle varies with temperature.
11, the instrument uses 5.7 inches color display, also shows two spectra, and is equipped with a touch screen.
