productDetail

GC-9560 is a gas chromatograph with optional electronic flow control (EPC) introduced by Shanghai Huaai Chromatography Analysis Co., Ltd. The instrument adopts large screen LCD liquid crystal display, which is intuitionistic and easy to operate.

 

At the same time, the instrument comes with its own digital interface, and realizes real-time data signal acquisition, data processing and two-way communication of the control commands of each unit of the instrument through a communication line. It is the first gas chromatograph in China to truly realize feedback control technology .

 

Technical features

1.Implement real-time control and data processing

Through the digital interface provided by the connecting instrument, GC-9560 data acquisition and control software in the computer can display a chromatogram in real time, and read the current state of the instrument and the set parameters, etc.

 

Through the software operation interface, it is greatly convenient for users to set parameters including temperature, Program data, detector, bridge electric current flow, etc. Also convenient to operate FID automatic ignition, switch bridge electric current flow, temperature control, turn off Program data and various other time events.

 

Expand t 10/1 OOM Ethernet interface ,and can be remotely controlled for convenient data collection and management.

 

2.High Precision, stable and reliable temperature control system

The main control circuit uses advanced microprocessors, large-capacity FLASH and EEPROM memory, for more reliable preservation of data. The integrated design of measurement, control and electrical source in the circuit board improves the anti-interference and reliability of the instrument.

 

using the temperature control circuit of microprocessor, the temperature precision of the controlled objects in each heating zone reaches 0.1 degree precision.

 

The column box has double overtemperature protection. Once the temperature beyond the setting, the instrument will stop heating, and report the fault on the display.

 

Intelligent double back door technology ensures that the instrument can have good temperature control accuracy even when the temperature of the column box is close to room temperature, and can quickly cool down.

 

Temperature rise program of eight orders is suitable for the analysis of complex samples with wide boiling point.

 

 

3.Concise and clear man-machine dialogue interface, easy to operate, easy to learn and use

 

The instrument adopts large-screen LCD Chinese character display technology, which is intuitive and easy to operate, and more suitable for China's national conditions.

 

Self - diagnosis function, can show fault location.

 

Touch-type keyboard convenient for setting the operation data.

The result report has two forms: analysis result and grouping result, which can edit the detailed information of samples and make the result report clear at a glance.

Real-time data and results can be exported to EXCEL or saved in an internationally standardized AIA file format.

Redrawing or recalculating can be done using other drawing tools or software. It can also be copied into the documents needed by users for the convenience of scientific researchers.

Peak locking function, which greatly facilitates users to determine the peak when there is deviation between the retention time and peak identification table time.
