More outstanding instrument performance
GC1120Yes, it isThe new gas chromatography developed on the basis of GC112A not only upholds the many qualities of GC112A, but also provides more advanced, precise, and higher technical specifications for ordinary functions.
Clear display screen at a glance
Large screen display, realizing Chinese menu style dialogue, making the display clearer and the operation simpler. It can display chromatograms, rise curves, and baseline levels, and simultaneously display the temperature settings and actual values of column boxes, injectors, detectors, etc. on one screen, providing more diverse and colorful instrument information.
Digital carrier gas flow monitoring system
The GC1120 pneumatic system can be equipped with an optional digital flow monitoring unit that displays the carrier gas flow rate and capillary branch flow rate values on the screen. It can display up to four sets of flow rates and automatically store flow parameters for easy recording and retrieval of analysis conditions. Convenient diversion adjustment and diversion ratio calculation, no need to use soap film flowmeter
Rich combinations of injector/detector units
Better expansion configuration to meet various needs. Choose more injector/detector series based on the diversity and complexity of the analyzed samples.
GC1120Four types of injectors can be configured from packed column injection unit, capillary split/non split injection unit, and up to three injectors can be loaded simultaneously.
GC1120Up to 6 high-performance detector options are available, including FID, TCD, ECD, FPD, NPD, and PID, and up to 3 detectors can be installed simultaneously. Additional detectors can also be used, making it easy to purchase and install other detectors after purchasing the instrument.
New built-in acquisition system
GC1120Advanced built-in acquisition device can collect instrument control status and chromatographic output signals, enabling real-time instrument control and data processing by connecting an external computer with a communication cable.
Real time control of instruments includes functions such as temperature control of various channels, selection and setting of detectors, programmed temperature rise control and range curve tracking, flow value display (optional), etc.
Data processing includes high-speed acquisition of dual channel (expandable to multiple channels) chromatographic data, automatic or manual setting of integration parameters, up to 5 quantitative methods, baseline deduction, report preparation, and other functions.
