Gas Chromatograph

Order Id: CH-GC-07
Categories: Chromatography  Gas Chromatography 

Instrument Introduction
The structure and performance of CH-GC-07 has been improved greatly. A new chromatograph system equipped with EPC and AFC technology is developed in response to the requirement of global GC technological development. Experience in producing international high-end gas chromatograph has also been introduced. Automation, intellectualization and multi- functionalization are realized on the prerequisite of ensuring the reliability and stability of the instrument..


Powerful control function
·All  parameters can communicate bi-directionally  through GC work station.
·Using powerful multi-CPU system to control correctly and stably.
·Adopting ARM9-32 micro chip .Memory is 64M .The system is capable of operating complicated graphics controlling function interface.
·8-way external event function supports multi-valve switch so that multidimensional chromatograph system is achievable.
·Automatic door open function makes ambient operation in the oven possible.

Highly sensitive PC control system & Reliable jamproof system & Perfect automatical operation
All parameters are transmitted by PC ; Remarkable automatic valve control and time programming; Automatic control ignition and automatic outfire function; Advanced autosampler system; Perfect data communication and processing function; Easy-learning operation; Simple optional autosampler,.All of these lead to the unattended GC analysis

Classical TFT large screen design makes the setting of parameter simple and intuitive.
Graphical display uses 8 inches 640×480 resolution TFT screens, which achieve the function of online monitoring and display of chromatograph elution curves perfectly..

Intellectualized self-diagnosis function makes breakdown retrieval simple
Prompt response to breakdown phenomenon, breakdown code and breakdown reason helps you to find and solve the problem as soon as possible and  guarantees the best condition of the  laboratory .

Remarkable Injection System, Realizing EPC and AFC technology through Capillary injection system
·Brand-new EPC and AFC technology; Digital control on all gas circuit parameter,; Stable flux and pressure precision ;  Programming pressure- rise chromatographic separation is applicable; Pressure precision is 0.0015psi; Retention time and peak area are highly repetitive.
·Many kinds of injectors and detectors solve difficult separation problem quickly. And it is convenient to choose. Split/splitless injection; Good linearity split; Discrimination phenomenon is rare; Quantity is accurate and saves the carrier gas.
