Types of Gas Chromatograph
| Capillary gas chromatography | Utilizes a narrow-bore column allowing for high-resolution separations. |
| Packed column gas chromatography | Employs a wider column filled with packing material, suitable for larger sample volumes. |
| Gc-ms (gas chromatography-mass spectrometry) | Integrates mass spectrometry for enhanced identification of components. |
| Pyrolysis gas chromatography | Analyzes solid samples by decomposing them through heat, then separating the resulting gases. |
Features of Gas Chromatograph
Chromatographic workstation can be connected, and the experimental results are intuitive and clear. User-Friendly Software – Intuitive interface for method setup, real-time monitoring, and data analysis (e.g., peak integration, calibration curves).
Flexible filling gas chromatography column and capillary column inlet design, can be selected according to the actual situation; The wide column box provides convenience for complex analytical tasks and the use of multiple columns to broaden the range of samples analyzed.
The use of microcomputer control, man-machine dialogue to draw a variety of required temperature column box temperature control range (room temperature +10℃)-300℃, temperature control accuracy of 0.1%. Gas leak detection, over-temperature protection, and automatic shutdown in critical conditions.
Applications of Gas Chromatograph
Environmental monitoring
Analyzing pollutants in air, water, and soil samples.
01
Pharmaceutical industry
Quality control of drugs and identification of impurities.
02
Food and beverage analysis
Determining flavor compounds and contaminants.
03
Petrochemical industry
Analyzing complex hydrocarbon mixtures.
04
Forensic science
Identifying drugs and toxins in biological samples.
05
Injector
The injector vaporizes the sample and introduces it into the carrier gas stream. It ensures the sample enters the column as a narrow band to maintain separation efficiency.
Column
The heart of the gas chromatograph, the column contains the stationary phase where separation occurs. Columns can be either packed or capillary, each with its own advantages.
Detector
As separated compounds elute from the column, the detector generates an electrical signal proportional to the quantity of each component. Various types of detectors are available, each suited for different applications.
Carrier gas system
This system provides a constant flow of inert gas (such as helium, nitrogen, or hydrogen) to carry the sample through the column.
Oven
The column is housed in a temperature-controlled oven, allowing for precise control of the separation conditions.
Data system
Modern gas chromatographs are equipped with computerized data systems for instrument control, data acquisition, and analysis.
