What type of chromatography uses a stationary liquid phase?

• A. Gas Chromatography
• B. Thin Layer Chromatography
• C. Liquid Chromatography
• D. Column Chromatography

Answer: (C)

The correct answer is indeed the type of chromatography that employs a stationary liquid phase, which is an integral part of the separation process in various chromatography techniques. Liquid chromatography specifically utilizes a liquid as the stationary phase, which interacts with the components of the sample mixture. In liquid chromatography, the sample is dissolved in a mobile phase, usually another liquid, which then carries it through a column where the stationary phase is either a liquid coated on solid particles or sometimes simply a liquid layer. The different components in the mixture will interact to varying degrees with the stationary liquid phase, leading to separation based on their affinities for that phase versus the mobile phase. This principle is essential for the purification and analysis of compounds in organic chemistry. While gas chromatography uses a gas as the mobile phase and typically a solid or polymer as the stationary phase, thin layer chromatography involves a solid stationary phase with a liquid mobile phase. Column chromatography can also use a solid stationary phase, where liquid can be the mobile phase that moves through the column. Therefore, when identifying a chromatography method that directly involves a stationary liquid phase, liquid chromatography is the most appropriate choice.
