Performance characteristics
1、 High circuit integration, high precision, multifunctional,
1. Fully computerized button operation, 5.7 inch (320 * 240) large LCD display in both Chinese and English, with free switching between Chinese and English displays, meeting the operational requirements of different groups. The human-machine dialogue mode is convenient for operation.
2. The microcomputer controlled hydrogen flame detector achieves automatic ignition function and is more intelligent. A brand new integrated digital electronic circuit with high control accuracy, stable and reliable performance, reaching a temperature control accuracy of 0.01 ℃.
3. Gas cut-off protection function, protecting chromatographic column, thermal conductivity cell and electron capture detector.
4. Equipped with power on self diagnosis function, allowing users to quickly know the cause and location of instrument faults, stopwatch function (convenient for flow measurement), power outage storage protection function, anti power mutation interference function, networked data communication and remote control function. The over temperature protection function ensures that the instrument is not damaged and has an advanced data memory system, eliminating the need for every reset.
2、 The unique design of the injection system allows for lower detection limits
1. Design of injection ports to address injection discrimination; The dual column compensation function not only solves the baseline drift caused by program heating, but also subtracts the influence of background noise to obtain a lower minimum detection limit.
2. Equipped with a packed column and capillary split/non split injection system (with diaphragm cleaning function)
3. Optional automatic/manual gas six way sampling valve injector, headspace injector, thermal analysis injector, methane conversion furnace, and automatic injector.
3、 Programmed heating, precise control of furnace temperature, stable and fast
1. The 10th order linear program temperature rise is achieved, and the rear door opening adopts a photoelectric switch contactless design, which is reliable and durable. The intelligent rear door opening system has stepless variable inlet and outlet air volume, shortening the stable balance time of each detector system after program temperature rise/drop. It truly achieves near room temperature operation, with a temperature control accuracy of ± 0.01 ℃, meeting the requirements of wide range analysis.
2. The column box has a large volume, and the intelligent rear door opening system has stepless variable inlet and outlet air volume, which shortens the stable balance time of each detector system after program heating/cooling; Heating furnace system: ambient temperature+5 ℃~420 ℃.
3. Better insulation effect: When the column box, vaporization, and detection are all at 300 degrees, the hottest point of the outer box and top cover is only 40 degrees, which improves the experimental speed and ensures the safety of users.
4. Unique vaporization chamber design with smaller dead volume; Replacement of accessories: The injection pad, liner, polarizer, collector, and nozzle can be replaced with one hand; Main body replacement: The filling column, capillary injector, and detector can be completely disassembled with just one wrench, making maintenance very convenient.
High sensitivity and stability detectors to meet the needs of different solutions
Hydrogen flame ionization detector (FID), thermal conductivity cell detector (TCD), electron capture detector (ECD), flame photometric detector (FPD), and nitrogen phosphorus detector (NPD) can be installed.
Various detectors can independently control temperature, and hydrogen flame detectors are easy to disassemble and install, making it easy to clean or replace nozzles.
