Description

GC-4000A series laboratory multi-purpose gas chromatographs are suitable for analysis of permanent gases and gases, liquids and gas-liquid mixtures with boiling
points below 400℃. It is widely used in petroleum, chemical industry, coal mine, food and environmental science, pesticide, health and epidemic prevention, quality
supervision, forensic chemistry and other fields.

feature

1.High efficiency
• Significantly reduce analysis time to provide high-speed, efficient analysis！
• Rich in self-diagnosis function, automatic alarm, quick troubleshooting！
• Automatic six-way valve sampling and automatic backblowing, pre-cutting device, high-speed special component analysis！
• Fast automatic heating program and fast automatic door cooling greatly improve work efficiency！
2.Easy operation
• The humanized Chinese user interface makes the operation more simple and
convenient.
• The large LCD screen on the host can display the temperature and operating
conditions in real time, which is more convenient and intuitive.
• It can not only analyze the setting of conditions through the touch keyboard of the host, but also flexibly and conveniently reverse control through the workstation
• Comprehensive Chinese online help system, so that users easier to operate and use. Extremely wide application range
• It provides optimal solutions for a wide range of analysis and application domains. High precision
• Excellent reproducibility of peak area and retention time
• sensitivity of the detector (TCD、FID、FPD、ECD、NPD) is greatly improved
• Extremely low noise and baseline drift. • The column temperature chamber with precise temperature control provides a stable
temperature environment for the effective separation of various components.
3.Flexibility and scalability

Detector

GC-4000A series gas chromatograph can be equipped with five of the most commonly used
detectors on the market. In order to meet the analysis needs of many industries and fields, at
least 32 different configurations of gas chromatographs have been formed by combining five
detectors and improving them according to the characteristics of different industries.

Five types of detectors

Detector Type	Application
TCD	Used for constant analysis of gas and liquid
FID	Used for analysis of organic compounds in hydrocarbon industry and other fields
FPD	Used for detection of trace sulfur and phosphorus compounds
NPD	Used for detection of trace nitrogen and phosphorus compounds
ECD	Detecting compounds that capture electrons
