◆New industrial design, simple and generous, unique and humanized GC control panel. The design of the interface takes into account the protection of user errors.
◆ EPC gas control adopts the third-generation EPC control unit patented by our company, with pressure or flow control mode. The purge valve is electronically controlled to minimize sample diffusion and loss. The split/splitless injection mode can meet various application requirements. The automatic air-saving function effectively reduces operating costs. The original instant valve switch technology with no dead volume eliminates the long wait for stable pressure when the valve switch is opened in the splitless injection mode. This effectively improves the peak shape and repeatability of the retention time.
◆The optimized GC temperature control system improves the accuracy of the oven temperature control to ±0.03℃, which improves the repeatability of the analysis. The built-in installation positions of nitrogen, hydrogen and air gas circuits can be compatible with other chromatographic detectors according to user needs. The repeatability of the temperature program has been improved, resulting in sharper peaks of heavy compounds in the oil.
◆The unique CI reagent gas flow control module adopts feedback control, which automatically adjusts the reagent gas flow rate to the optimal level in proportion to the preset CI gas target ion, thereby saving the reagent gas while ensuring the high repeatability of the CI analysis.
◆Simple and practical direct liquid and solid injection probe options can perform rapid structural analysis of unknown compounds, providing a powerful tool for chemical synthesis applications. The unique detachable probe heater is easy to replace in case of damage or contamination. The highest temperature is 650°C.
◆Compatible with standard conventional GC columns.
◆Optional autosampler.
◆The software can be configured with a variety of optional peripheral accessories. Purge and trap concentrator, liquid autosampler, thermal desorption, headspace sampler, etc. can be easily set up, configured and controlled. Additional DO (digital output) port can be used for external device control
◆The innovative rotatable liquid autosampler can rotate 360° on the horizontal surface. The autosampler can be easily removed from the holder to simplify GC maintenance.
