What is the difference between partition chromatography and adsorption chromatography?
The partition chromatography involves separation between liquids while adsoption chromatography involves solid and liquid separations. Answer: Partition Chromatography is a liquid liquid extraction which involves two solvents while adsorption chromatography is a liquid solid extraction which involves a solid stationary phase & a liquid mobile phase.

RafaPartition chromatography separates compounds based on their relative solubility in two immiscible phases, typically a mobile phase and a stationary phase. Adsorption chromatography separates compounds based on their adsorption onto a solid stationary phase. In partition chromatography, solute molecules distribute between the two phases, while in adsorption chromatography, molecules interact with the surface of the solid stationary phase.
Paper chromatography is a classical example of partition chromatography as the separation of the analyte occurs by the process of partition between the water molecules (present in the interstices of the cellulose of which the paper is made of) serving as liquid stationary phase and any solvent used as mobile phase.

What difference between dad and uv detector in hplc?
Liquid chromatography (LC) encompasses all chromatographic techniques using liquid mobile phase, including planar chromatography (paper chromatography and thin-layer chromatography) and column chromatography (classical column chromatography, and high-performance liquid chromatography on packed and capillary columns). The term liquid chromatography is nowadays often used as a sinonim for high performance liquid chromatography (HPLC) and ultra-high performance liquid chromatography (UHPLC).
Principle of partition chromatography?
Partition chromatography separates compounds based on their partitioning between stationary and mobile phases. As the compound moves through the stationary phase, it distributes itself between the two phases, resulting in differential migration rates and separation of the compounds. The principle relies on differences in partition coefficients of the compounds in the two phases.
What is difference between high pressure liquid chromatography and high performance lequid chromatography?
High pressure liquid chromatography (HPLC) and high performance liquid chromatography (HPLC) are often used interchangeably. HPLC refers to modern liquid chromatography systems with high resolution and efficiency, while high pressure liquid chromatography specifically highlights the use of higher pressures in the system to improve separation and speed. Both terms generally refer to the same chromatographic technique.
What are examples of partition chromatography?
Examples of partition chromatography include gas-liquid chromatography (GLC), liquid-liquid chromatography (LLC), and paper chromatography. These techniques rely on the differential partitioning of analytes between two immiscible phases to separate chemical compounds in a mixture.
What is the difference between flash chromatography and column chromatography?
Column chromatography, is a broad term for all column chromatography methods, but is also synonomous with Gravity fed methods. Flash chromotography refers specifically to a column in which the eluant (or mobile phase) is moved through the column under pressure (using a hand pump for small scale, or a pressurised gas for a larger scale), the name Flash is derived from how much faster it is to run a column under pressure than via gravity.
