Hydrogen gas used for laboratory gas chromatography are the main following:
1.Hydrogen gas is used as the carrier gas for gas chromatography analysis for sample separation and analysis.
2.When using capillary columns for analysis, it is generally necessary to use the same gas as the carrier gas as the tail blowing gas.
3.When using FID, FPD, and NPD as detectors, hydrogen gas is used as fuel gas and burned with air to form flame.
In addition, when the instrument uses a conversion furnace, additional hydrogen gas is required to react with CO and CO2 to generate methane.
The common hydrogen supply methods include the use of hydrogen gas cylinder and the use of a hydrogen generator.
Gas Chromatography is an efficient separation and analysis technology that can separate various components in chemical mixtures and detect their composition. Gas chromatography requires the use of high-purity gas as the carrier gas for analysis. Hydrogen is one of common type as it can provide sufficient flow rate and resolution.
Lab hydrogen generator is a device used to produce high-purity hydrogen gas. It prepares high-purity hydrogen gas through water electrolysis or metal catalysis, providing stable carrier gas with flow rate and purity for gas chromatography analysis.
Gas chromatography requires the use of a carrier gas to avoid sample adhesion in the column. High purity hydrogen gas is one of the essential carrier gases in gas chromatography, and is widely used due to its fast diffusion, good resolution, and low inertness. High purity hydrogen gas ensures the performance of gas chromatography analyzers, ensuring the accuracy and reliability of analysis results.
Hydrogen generator provides high-purity and stable hydrogen gas for gas chromatography, and ensures the required hydrogen flow rate for routine analysis. The high-purity hydrogen gas is transported through pipelines to the gas chromatography for sample separation and detection. Compared with traditional gas cylinders, hydrogen generator is widely used in laboratories as its feature of lower cost, higher efficiency, and safe.
