Instrument characteristics
The instrument adopts Internet communication technology, which can easily form a LAN; Internet enables remote data transmission, remote control, remote diagnosis, and automatic program upgrade.
Fully computerized button operation,5.7Large screen size13LCD Chinese display, human-machine dialogue mode, easy to operate.
Newly integrated digital electronic circuit with high control accuracy, stable and reliable performance, and temperature control accuracy up to0.1.
Unique injection port design solves injection discrimination; The dual column compensation function not only solves the baseline drift caused by program temperature rise, but also reduces the influence of background noise to obtain a lower minimum detection limit.
Large column box volume:300×280×180 Can accommodate two at the same time80mCapillary chromatography column.
Better insulation effect: column box, vaporization, and detection are all300°CAt that time, the hottest spots on the outer box and top cover were only40°CImprove experimental speed and ensure user safety.
The unique logarithmic amplifier technology design can amplify weak signals with high gain, and automatically reduce the gain of strong signals to avoid saturation.
Unique vaporization chamber design with smaller dead volume; Accessory replacement: The injection pad, liner, polarizing electrode, collection electrode, and nozzle can all be replaced with one hand; Main body replacement: packed column, capillary samplerTCD、FIDThe detector can be completely disassembled with just one wrench, making maintenance very convenient.
The intelligent rear door opening system has stepless variable air flow in and out, shortening the system's stable balance time after program temperature rise/fall.
Can install two injection systems simultaneously:Fill column, capillary diversion/Non split injection system (with diaphragm cleaning function); Four identical or different detectors can be installed simultaneously: withFID、TCD、ECD、FPDandNPDDetector. Optional automatic/manual gas six way injection valve injector
Headspace sampler, thermal analysis sampler, cracking furnace sampler, methane converter.
It has powerful and comprehensive startup self diagnostic function, intuitive display of fault information, power-off storage protection function, keyboard locking function, automatic ignition function, and anti power mutation interference function.
