The stationary phase is the medium that is used to react with the mobile phase. The molbile phase is sent through the column. The stationary phase is inside the column and reacts with your carrier liquid (mobile phase) which contains the sample that you want to be analyzed.
Stationary phase is different for every column because you need different mediums for different tests.

How does a gas liquid chromatography work?
Gas liquid chromatography separates components of a mixture based on differences in their interaction with a stationary phase and a mobile gas phase. The sample is vaporized and carried through a column by an inert gas, where it interacts with the stationary phase. Components with stronger interactions take longer to travel through the column, causing them to separate and be detected at different times.
What kind of species can be separated by high performance liquid chromatography but not gas chromatography?
Polar and non-volatile compounds, such as large biomolecules like proteins or carbohydrates, can be separated by high performance liquid chromatography but not gas chromatography due to differences in their chemical properties and interaction with the stationary phase. Gas chromatography is more suitable for separating volatile and non-polar compounds based on their volatility and interaction with the stationary phase.
What chromatography separates lipids?
Thin-layer chromatography (TLC) and gas chromatography (GC) are commonly used to separate lipids based on their chemical properties such as polarity and volatility. TLC separates lipids based on their partitioning between a stationary phase and a mobile phase, while GC separates lipids based on their boiling points and vapor pressures in a gas phase.
What are the different types of chromatography?
there are different types like gas chrom. and thinlayer chrom Answer: There are two types of chromatography:liquid chromatography gas chromatography
Why is gas-liquid chromatography also called vapor-phase chromatography?
Gas-liquid chromatography is also called vapor-phase chromatography because it involves the separation of components of a sample based on their volatility in the vapor phase. In this technique, a gas (typically an inert carrier gas) is used to carry the sample through a liquid stationary phase, where separation occurs based on differences in partitioning between the gas and liquid phases. By using a volatile mobile phase, gas-liquid chromatography allows for the analysis of compounds with relatively low boiling points.

What called mobil phase?
The mobile phase is the liquid or gas that flows through the chromatography system, carrying the sample to be separated. It moves over the stationary phase (solid or liquid) and helps separate the components based on their interactions with the stationary phase. The choice of mobile phase depends on the type of chromatography being performed.

Principle of partition chromatography?
Chromatography in which separation is based mainly on differences be- tween the solubility of the sample components in the stationary phase (gas chromatography), or on differences between the solubilities of the compo- nents in the mobile and stationary phases (liquid chromatography)
What is difference bet GLC and HPLC?
GLC has a stationary liquid phase and gas moving phase HPLC had a stationary solid phase and liquid moving phase HPLC is done under high pressure. HPLC can be used for thermally unstable compounds as opposed to GLC HPLC can be used for polar or low volatile compounds as opposed to GLC
What separates substances based on their movement through a special paper?
Chromatography separates substances based on their differing abilities to dissolve in a mobile phase (usually a liquid or gas) and adhere to a stationary phase (such as special paper). As the mixture is carried along by the mobile phase, components with stronger affinity for the stationary phase will move slower, leading to separation based on their solubility and adsorption properties.
What factors can affect the adjusted retention time in gas chromatography?
Factors that can affect the adjusted retention time in gas chromatography include the type of stationary phase, the temperature of the column, the flow rate of the carrier gas, and the chemical properties of the analyte being separated.
Why it is called chromatography separation?
Chromatography is called a separation technique because it separates different components of a mixture based on their different affinities for the stationary phase (solid or liquid) and the mobile phase (gas or liquid). As the mixture passes through the stationary phase, the components interact differently and move at different rates, leading to separation.
What is the stationary phase in DB-624?
In DB-624, the stationary phase is a phenyl arylene polymer that has a 6% cyanopropyl substituent. This phase is commonly used in gas chromatography for separating a wide range of analytes, especially non-polar and moderately polar compounds.
