The instrument has better performance

GC1120 The gas chromatograph is GC112A Based on the new gas chromatography launched, it not only adheres to GC112A Many excellent qualities in turn make ordinary functions more advanced, more precise and higher technical specifications.

Display the screen clearly at a glance

A large-screen monitor realizes Chinese menu-style dialogue, making the display clearer and easier to operate. It can display the chromatographic spectrum, the progression curve, the base current level, and display the temperature set values ​​and actual values ​​of column boxes, samplers, detectors, etc. in one screen, which can provide more colorful instrument information.

Digital carrier gas flow monitoring system

GC1120 The gas circuit system can be equipped with the latest digital flow monitoring unit, which displays the carrier gas flow and capillary shunt flow value through the screen, and can display up to four sets of flows, and the flow parameters can be automatically stored to facilitate the recording and call of analysis conditions. Convenient flow regulation and flow ratio calculation without the use of a soap film flowmeter

Rich sample injectors /Detector unit combination

A better expansion configuration can meet various needs. Select more injectors based on the diversity and complexity of the analytical samples /Detector series.

GC1120 Can be diverted from the filling column injection unit and capillary /The split-free injection unit realizes the configuration of 4 kinds of injectors, and up to 3 injectors can be loaded at the same time.

GC1120 Up to 6 high-performance detector options are available, i.e. FID、TCD、ECD、FPD、NPD and PID， Up to 3 detectors can be installed simultaneously. You can also use the detector addition method to easily purchase and install other detectors after the instrument is purchased.

Brand new built-in acquisition system

GC1120 The advanced built-in acquisition device can collect instrument control status and chromatographic output signals, enabling the use of a communication line to connect to external computers for real-time instrument control and data processing.

Real-time instrument control includes various temperature control, detector selection and setting, program temperature increase control, process increase curve tracking, flow value display (optional).

Data processing includes high-speed acquisition of dual-channel (scalable to multi-channel) chromatographic data, automatic or manual setting of integral parameters, up to 5 quantitative methods, baseline deduction, report preparation and other functions.

Note: The above are commonly used configurations. Users can make any configuration combination according to special needs. Please explain it when ordering.
