Adopting 10/100M adaptive internet communication technology, it can form a local area network with high communication efficiency; Realized long-distance data transmission; One chromatograph can connect to three computers; One computer can simultaneously connect multiple chromatographs (up to 5000) and perform operational control.
2. Countercontrol
All instrument parameters can be set remotely through a computer and spectrogram processing can be performed.
3. Full EPC/EFC control
Adopting a brand new automatic flow/pressure control technology, the digital control of all gas circuit parameters (flow and pressure), the working mode is divided into three types: constant flow, constant pressure, and split flow. Can perform 4-stage program boosting, with a pressure accuracy of 0.01KPa and a flow rate of 0.01sccm.
4. Touch screen
The instrument adopts a large touch color screen, which displays intuitively and is easy to operate.
5. Fast temperature rise and fall speed
Equipped with a fast temperature rise and fall structure, capable of achieving a heating rate of 80 ºC/min; Realize work at room temperature environment; Under liquid nitrogen conditions, support a wide range of temperature control from -80 ºC to 450 ºC.
6. Automatic ignition, automatic detection and fire extinguishing
Adopting intelligent hydrogen and air automatic control technology, the electromagnetic valve automatically switches on and off the gas, thereby achieving true automatic ignition function.
