Hydrogen is the carrier gas for the sample in the GC. Hydrogen is a very light weight and cheap gas. Hydrogen consists of only 1 proton and 1 electron... each of these weigh very little and this is the reason it is used as a carrier gas.
Other carrier gases could be helium, nitrogen, argon, and just plain air. Each of these has a advantage to use and a disadvantage. Some gases may react with the sample being analyzed. That is why most of the carrier gases are inert gases.

Why hydrogen is used carrier gas?
Hydrogen is used as a carrier gas in gas chromatography because it has good thermal conductivity, low density, and high diffusivity. This allows for high separation efficiency and faster analysis times. Additionally, hydrogen is inert and compatible with most detectors used in gas chromatography.
How can hydrogen be detected?
Hydrogen can be detected using several methods, including gas sensors, gas chromatography, and mass spectrometry. Gas sensors are commonly used for detecting hydrogen leaks in industrial settings, while gas chromatography and mass spectrometry can provide more precise measurements of hydrogen concentrations in a sample.
Gas chromatography for the detection of hydrogen?
Gas chromatography is a technique used to separate and analyze components in a gas sample. It works by passing the gas sample through a column where the different components are separated based on their interactions with the column material. Detection of hydrogen in gas chromatography is typically done using a thermal conductivity detector, which is sensitive to changes in thermal conductivity caused by the presence of different gas components.

How do you check the hydrogen gas purity?
One common method to check the purity of hydrogen gas is through gas chromatography, where the components of the gas mixture are separated and identified. In addition, purity can be verified using specific sensors or detectors designed to measure the presence of impurities in the gas. It's important to use calibrated equipment and follow proper procedures to ensure accurate results.

No, they are different techniques.
What are similar properties to Hydrogen?
Helium, a colorless, odorless, and non-toxic gas, has similar properties to hydrogen, including being the lightest gas, having low density, and being chemically inert. Both helium and hydrogen are commonly used in applications such as gas chromatography, cryogenics, and as lift gases in balloons.
