GC-4100 series gas chromatograph Introduction
Many technologies of GC-4100 series gas chromatograph are significantly improved on the basis of GC-4000A. The whole machine realizes computer workstation control, and can realize EPC electronic flow control of six channels of gas (the number of gas channels can be expanded), including Gas, auxiliary gas, split flow and makeup gas are controlled. Detector and oven temperature control uses fuzzy PID intelligent control. Features
High automation and high efficiency
1.The whole machine is controlled by computer.
2.Rich self-diagnosis and alarm functions.
3.Automatic six-way valve sampling, automatic backflushing, pre-cutting device, septum purge and other functions realize various special analyses.
4.Ten-step program temperature increase; the door opening mechanism is controlled by the microcomputer of the oven to realize rapid automatic program temperature increase and rapid automatic temperature decrease to improve work efficiency.
Easy to operate
5.Humanized Chinese user interface makes the operation easier and more convenient.
6.The large LCD screen on the main unit can display the temperature and operating conditions in real time, which is more convenient and intuitive.
7.Not only can set the analysis conditions through the touch keyboard of the host, but also can control the host flexibly and conveniently through the workstation software.
8.Online help system in Chinese to make it easier for users to operate and use.
High precision
9.Excellent reproducibility of peak area and retention time.
10.Increased detector sensitivity, low noise, and low baseline drift.
11.With eight independent temperature control zones (column, sampler, thermal conductivity, hydrogen flame and other detectors), the accurate temperature controlled column temperature chamber provides a constant temperature environment for the effective separation and detection of various components.
Flexibility and scalability
12.Three detectors, three inlets, and three columns can be installed simultaneously.
13.Can have three independent circuits, pneumatic system and three signal output terminals at the same time.
14.Large-volume column thermostat, which can install glass, stainless steel packed column and capillary column and other chromatographic columns at the same time.
15.Flexible and diverse sampling methods. Capillary split / splitless injection, packed column injection, and cold on-column injection.
16.Flexible syringe sampling system, with optional autosampler or six-way valve sampling.
17.Automatic backflushing, automatic carrier gas switching, septum purge, and one-shot automatic full analysis system.
18.Methane reformer, cracking furnace, thermal analysis, purge and trap system.
19.The diverter outlet is designed with a collection tube to protect the EPC and create a clean and safe laboratory environment.
20.Can be reserved for use with mass spectrometry channels (according to customer requirements).
21. A wide range of applications, providing solutions for multiple analysis areas. Technical parameters
