Gas chromatograph GC-4100

Instrument Features
The GC-4100 series gas chromatograph is a new generation product developed and produced by Beijing Dongxi Analytical Instrument Co., Ltd. Multiple technologies have been significantly improved on the basis of GC-4000A, and the entire machine is controlled by a computer workstation. It can achieve EPC electronic flow control for six gas channels (with expandable gas channels), including control of carrier gas, gas, auxiliary gas, diversion, and tail gas. The detector and column box temperature control adopt fuzzy PID intelligent control, creating a new gas chromatography temperature control system.
High automation and efficiency
The whole machine is computer-controlled.
Rich self diagnosis and alarm functions.
The functions of automatic six way valve injection, automatic back blowing, pre cutting device, and gasket blowing enable various special analyses.
Ten step program heating up; The column box microcomputer controls the rear door opening mechanism to achieve rapid automatic program heating and rapid automatic cooling, greatly improving work efficiency.
Easy to operate
Humanized Chinese user interface makes operation simpler and more convenient.
The large LCD screen on the host can display temperature, operating conditions, etc. in real time, making it more convenient and intuitive.
Not only can the analysis conditions be set through the touch keyboard of the host, but also the host can be flexibly and conveniently controlled through the workstation software.
The all Chinese online help system makes it easier for users to operate and use.
high precision
Excellent reproducibility of peak area and retention time.
The sensitivity of the detector has been significantly improved, with extremely low noise and minimal baseline drift.
Equipped with eight independent temperature control zones (column box, sampler, thermal conductivity, hydrogen flame detector, etc.), the precisely controlled column temperature box provides a constant temperature environment for effective separation and detection of various components.
Flexibility and scalability
Can simultaneously install any three detectors, three injection ports, and three chromatography columns.
It can simultaneously have three independent circuits, pneumatic systems, and three signal output terminals.
Large volume column temperature chamber, capable of simultaneously installing chromatography columns such as glass, stainless steel packed columns, and capillary columns.
• Flexible and diverse injection methods. Capillary split/non split injection, packed column injection, cold column head injection.
Flexible syringe injection system, optional with automatic injector or six way valve injection.
Automatic backflushing, automatic switching of carrier gas, gasket blowing, and one-time injection automatic full analysis system.
• Methane conversion furnace, cracking furnace, thermal analysis, blowing and capturing device system.
The diversion outlet is designed with a dedicated capture pipe to protect the EPC and create a clean and safe laboratory environment.
Reserved channels for mass spectrometry (according to customer requirements).
Extremely wide range of applications, providing optimal solutions for numerous analytical fields.
