The main function
1. The display adopts a vacuum fluorescent display, which can be switched between Chinese and English.
2. Through keyboard operation, various parameters and methods can be set.
3. The communication interface board is connected with the chromatographic workstation to realize the chromatographic workstation to counter-control the chromatograph.
4. More than 16 sets of chromatographic methods can be stored.
5. It has an external power supply voltage microcomputer detection system and an over-temperature protection system to ensure that the microcomputer will not crash and the temperature will not run out of control.
6. It has 8-channel high-precision temperature control system and 8-channel external event function, supports multi-valve multi-column switching, and realizes simple analysis of complex samples.
7. The oven has a temperature program function of any step, and the reproducibility is better than 0.5%. At the same time, the excellent automatic rear door opening function enables the oven to operate near room temperature. The oven can achieve 450℃ high temperature control, and has a liquid nitrogen/dry ice introduction system to achieve low temperature control.
8. All temperature, pressure, flow and events are digitally controlled and displayed.
9. It has multiple injection systems, including packed column injection system, capillary column injection system and valve injection system, which can realize the simultaneous analysis of packed column and capillary column.
10. The capillary column sampler has an 8-step temperature program function, and the reproducibility is better than 1%. After the temperature program stops, semiconductor or air cooling is used.
11. The capillary sampling system has split/splitless injection function, and can run gas saving mode.
12. The system of cleaning packed column with diaphragm realizes the trace analysis of packed column chromatography.
13. High-sensitivity, high-stability multi-detector system (TCD, FID, ECD, FPD, NPD), 3 detectors can be installed at the same time (optional).
14. FID realizes wide-range technology to enhance the scope of analysis application.
15. The detector board outputs analog and digital signals at the same time, and both analog and digital signals can be automatically zeroed.
16. The column flow can realize any constant pressure or constant flow control.
GC97 Series Counter-control Chromatographic Workstation
1. A high-performance multi-channel, multi-user universal chromatographic workstation, which fully controls the working parameters of the chromatograph.
2. One to four independent detector signals can be collected at the same time.
3. Various forms of high-precision chromatographic signal acquisition, data transmission via RS232 and USB.
4. Support Simplified Chinese or English Windows32 operating system.
5. Sampling frequency: maximum 100Hz
6. Number of peaks that can be processed: unlimited
7. Integral sensitivity: 1uV*s
8. Dynamic range: 220
9. Fully support FDA-21CFR Part11 certification (electronic signature, record, user password), system suitability test (SST) and system certification tools (IQ/OQ).
10. The batch processing function makes the instrument control, autosampler sequence collection, automatic integration correction and report output all-in-one, simplifying the daily tedious analysis.
11. Powerful post-processing functions, chromatogram comparison, re-correction, data input and output and other functions are all available. "Snapshot" can get the analysis results online without waiting until the end of the collection.
