All by microcomputer control and management, high reliability design, reflecting excellent quality performance, greatly improve the efficiency of analysis.
New EPC electronic gas path control, high-precision valve control electronic pressure display, high-precision valve control meter display (1 of 3)
GC-2987-Y PLUS integrated EPC module for accurate and stable flow and pressure control, digital control of the injector and detector gas path parameters, to ensure the consistency and reproducibility of analysis results.
According to different needs of customers, 1-5 EPC modules can be installed at the same time to achieve EPC control of 3-15 channels.
Carrier gas flow accuracy ±5%, flow repeatability ±0.35%, flow range 200ml/min. And there are standardized atmospheric pressure and temperature compensation, program pressure and flow program functions.
The new EPC electronic gas path control technology provides a guarantee for excellent retention time repeatability accuracy.
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.
Various high performance injection ports
The GC-2987-Y PLUS offers a variety of injector options, including shunt/non-shunt capillary injector and filled column injector, to optimize chromatographic separation.
Can install two shunt/non-shunt inlet, or one shunt/non-shunt inlet and one bulk inlet, or one capillary inlet and one filling column inlet, all under EPC control.
Shunt/non-shunt inlet, with smaller dead volume and higher repeatability, can choose up to more than 10 kinds of international general glass lined pipe.
Optional different number of automatic liquid injector, headspace automatic injector, thermal desorption instrument, simple and easy to operate, and high stability.
High efficiency column box with precise temperature control and excellent temperature performance
GC-2987-Y PLUS chromatograph chamber temperature performance reaches the international advanced level. With high precision temperature control system, it can meet the fast and accurate constant temperature and programmed temperature control.
The large-capacity column box is equipped with a capillary column. In special cases, two capillary columns, or two filled columns and one capillary column can be installed at the same time.
Temperature control dynamic range from ambient temperature +4ºC to 450ºC, temperature stability up to ±0.02ºC. Support 20 order column box temperature gradient, through software Settings can also be arbitrarily increased.
Eight way temperature control, any way over temperature automatically cut off the power to stop heating and alarm
Adaptable to a wide range of GC workstation software (built-in host)
High-performance, self-developed GC software, can achieve GC-2987-Y PLUS two-way control and data processing, more friendly and simple operation.
English workstation software, using task and method models, provides a flexible combination to suit a variety of workflows and applications.
Optional high sensitivity series amplifier
All amplification controllers of GC-2987-Y PLUS use counter-control data, and all parameters are set and modified by computer to truly achieve full counter-control.
FID amplifier adopts international common logarithmic amplifier to improve FID sensitivity and reproducibility.
TCD constant current control board, using constant current control mode, the maximum current is 220mA, greatly improving the sensitivity and stability.
High sensitivity detector series
All GC-2987-Y PLUS detectors use EPC control, FID automatic ignition, fire extinguishing prompt, fire extinguishing automatic key functions, including air: 0-800ml/min, hydrogen: 0-100ml/min, tail blowing: 0-100ml/min. At the same time, the advanced detector control circuit can realize the digital data output of the full range.
GC-2987-Y PLUS not only optional five kinds of detectors, such as FID, TCD, FPD, ECD, NPD and other detectors, but also can connect the mass spectrum detector. Suitable for all types of sample analysis and detection needs.
Reserved MS connection interface, can be upgraded to GTC-MS system.
