All controlled and managed by microcomputers, high reliability of the design, reflecting excellent quality performance, improve the efficiency of analysis.
New EPC electronic air circuit control, high-precision valve control electronic pressure display (one of two)
The all-in-one EPC module of the GC-9870 Plus is accurate and stable for flow and pressure control, and digitally controls the air path parameters of the sampler and detector, ensuring the consistency and reproducibility of the analysis results.
According to the different needs of customers, 1-5 EPC modules can be installed at the same time to achieve 3-15 channels of EPC control.
The accuracy of the air-carrying flow is 5%, the flow repeatability is splusmn; 0.35%, the flow range is 200ml/min. And there is standardized atmospheric pressure and temperature compensation, program pressure and flow program function.
The new EPC electronic air circuit control technology guarantees excellent retention time repeat accuracy.
High-precision valve control regulation, color spectrum host display and computer anti-control software real-time electronic digital pressure display, to ensure the accuracy of adjustment, to achieve the repeatability of the instrument.
A wide range of high-performance samples
The GC-9870 Plus offers a variety of sample inlet options, including shunt/non-shunt capillary inlet, and fill column inlet ports to optimize chromatography separation.
Can install two shunt / non-shunt inlet, or a shunt / non-shunt inlet and a large volume inlet, or a capillary inlet and a filled column inlet, all using EPC control.
Shunt/non-shunting sample, with smaller dead volume and higher repeatability, can choose up to more than 10 kinds of international common glass lining tube.
Optional automatic liquid sampler with different digits, overhead automatic sampler, thermal suction meter, easy to operate, and high stability.
Precision temperature control, high-efficiency column box with excellent temperature performance
The chromatograph column chamber temperature performance of the GC-9870 Plus has reached the international advanced level. With high-precision temperature control system, it can meet the fast and accurate temperature temperature and procedure heating control.
The large-capacity column box is equipped with a capillary column, and in special cases two capillary columns can be installed at the same time, or two filling columns and one capillary column.
The temperature control dynamic range from the ambient temperature of 4 degrees C to 420 degrees C, temperature stability of up to plusmn; Support slower heating gradient, through software settings can also be arbitrarily increased.
Eight-way temperature control, either way super-temperature automatically cut off the power supply to stop heating and alarm
Adapttos a wide range of GC workstation software (built-in host)
High-performance, self-developed GC software, the GC-9870 Plus can achieve two-way control and data processing, more friendly and simple operation.
All-Chinese workstation software, using task and method mode, to provide a flexible combination, suitable for a variety of workflows and applications.
Optional high-sensitivity series of amplifiers
All the GC-9870 Plus amplification controllers use anti-control data, all parameters are computer set and modified, and truly achieve full back control.
THE FID AMPLIFIER USES THE INTERNATIONAL LOG AMPLIFIER, WHICH IMPROVES FID SENSITIVITY AND REPRODUCIBILITY.
TCD constant current control plate, using constant current control mode, current maximum 220mA, improve sensitivity and stability.
High-sensitivity detector series
All GC-9870 Plus detectors fully use EPC control, FID, FPD automatic ignition, fire warning, fire extinguishing automatic focus function, wherein air: 0-800ml/min, hydrogen: 0-100ml/min, tail blow: 0-100ml/min. At the same time, advanced detector control circuitry enables full-scale digital data output.
The GC-9870 Plus not only selects five detectors, such as FID, TCD, FPD, ECD, NPD and other detectors, but also connects mass spectrometry detectors. Suitable for all types of sample analysis and testing needs.
Reserved MS connection interface, can be upgraded to GTC-MS system.
