GC-4000A Series Gas Chromatographs can be used in analysis of a wide range of chemicals, from ambient temperature gases to liquids and gas-liquid mixtures with boiling points of 400℃ or lower. This extremely versatile instrument has many applications in industries such as oil, coal, chemical engineering, environmental protection, textile, agriculture, medicinal research, and sanitation.

Technical specifications:

1. We offer five types of detectors. Each is designed to fit the customers' special needs.
√ Flame Ionization Detector (FID): used for highly sensitive organic compound analysis.
√ Thermal Conductivity Detector (TCD): analyzes ambient temperature gases, water, and small hydrocarbon compounds.
√ Flame Photometric Detector (FPD): used in analysis of pesticide traces, sulfur and phosphorous compounds.
√ Electron Capture Detector (ECD): for detecting pesticides, and chlorine-containing compounds.
√ Nitrogen-Phosphorus Detector (NPD): ideal for analyzing trace quantities of nitrogen and phosphorus.
2. With unit type monolithic construction design, it is easy to the installation and maintenance.
3. Outfitted with large column oven, three columns can be installed simultaneously.
4. Reasonably designed, the instrument may install three kinds of detectors of different types simultaneously. In addition, it has three independent electro circuit systems and three signal output fan-outs.
5. Flexible packed column and capillary column system.
6. Stable temperature control system; 8 ramp programmable heating; the sample injector and every detector may control the temperature independently and has over temperature protection function.
7. Fire new regulating and multi-gas system; single, double and three gas path can be chosen discretionarily.
 Injector and valve sample injection system are outfitted or chosen discretionarily.
 Reversible flow and pre incision device can be chosen discretionarily. 
   Methane reforming furnace and cracking furnace are to be chosen freely.
