Product Description GC-9870 Touch Color Screen Plus Reverse-controlled EPC Gas Chromatograph Gas Detection InstrumentSummaryGC-9870 Plus gas chromatograph (touch color screen) uses fully reversed-controlled EPC electronic gas path control and high precision temperature control, combined with optimized column temperature chamber and sampler, to provide an excellent performance chromatographic separation system.GC-9870 Plus fully reverse-control EPC automatic gas chromatograph, using imported (1280X800) color touch screen setting and display, friendly interface, simple operation. All by microcomputer control and management, high reliability design, reflect excellent quality performance, improve the efficiency of analysis. GC-9870 Touch Color Screen Plus Reverse-controlled EPC Gas Chromatograph Gas Detection Instrument FeaturesNew EPC electronic gas path control, high precision valve control electronic pressure display (choose one of two)1.GC-9870 Plus integrated EPC module for accurate and stable flow and pressure control, digital control of injector and detector gas path parameters, to ensure the consistency and reproducibility of analysis results.2. According to different requirements of customers, 1-5 EPC modules can be installed at the same time to realize EPC control of 3-15 channels.3. Carrier gas flow accuracy ±5%, flow repeatability ±0.35%, flow range 200ml/min. And has standardized atmospheric pressure and temperature compensation, program pressure and flow program functions.4. New EPC electronic gas path control technology, to obtain excellent retention time repeatability accuracy to provide a guarantee.5. High precision valve control adjustment, chromatography host display and computer counter-control software real-time electronic digital pressure display, to ensure the accuracy of regulation, to achieve the repeatability of the instrument. High efficiency column box with precision temperature control and excellent temperature performance1.GC-9870 Plus chromatograph column chamber temperature stability. With high precision temperature control system, it can meet the fast and accurate constant temperature and programmed temperature control.2. Large-capacity column box is equipped with one capillary column. In special cases, two capillary columns, or two packed columns and one capillary column can be installed at the same time.3. Dynamic temperature control range from ambient temperature +4oC to 420oC, temperature stability up to ±0.02oC. Support 20 column box temperature gradient, through the software setting can also be arbitrarily increased.4. Eight way temperature control, any overtemperature automatically cut off the power to stop heating and alarm Optional high sensitivity series amplifier1. All amplification controllers of GC-9870 Plus use reverse control data, all parameters are set and modified by computer, truly realize full reverse control.2.FID amplifier uses logarithmic amplifier to improve FID sensitivity and reproducibility.3.TCD constant current control board, using constant current control mode, current up to 220mA, improve the sensitivity and stability.
