GC-9870 Plus Gas Chromatography Analyzer gas chromatography instrument for EO Residue Detection
GC-9870 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 420ºC, temperature stability up to ±0.02ºC. Support 20 order column box temperature gradient, through software Settings can also be arbitrarily increased.
8-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-9870 Plus two-way control and data processing, more friendly and simple operation.
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-9870 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
GC-9870 Plus all detectors are fully controlled by computer, FID, FPD 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-9870 Plus is not only equipped with five detectors, such as FID, TCD, FPD, ECD, NPD and other detectors, 8 independent external events. Suitable for all types of sample analysis and detection needs.
Reserved MS connection interface, can be upgraded to GTC-MS system.
