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.
Partition 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.
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.
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.

The difference between partition to classification?
Classification is sorting out things due to scientific process. Partition is eminent domain.
Explain the difference between the windows boot partition and the windows system partition?
The system partition is the active partition of the hard drive and it contains the OS boot record. The boot partition is the partition where the Windows operating system is stored.

What is difference between adsorption and biosorption?
Adsorption is the process by which a substance is attached to the surface of a solid material. Biosorption, on the other hand, involves the use of living or dead biomass to remove pollutants from a solution. Biosorption is a specific type of adsorption that relies on biological processes to remove contaminants.
What is the difference between Hard partition and Soft partition in Mac OS X?
A hard partition restructures the disc and each partition is recognised as a separate disc. A soft partition allows the operating system to recognise the partitions as separate discs but without changing the structure of the drive. Remember to always backup the contents of a disc before partitioning - even with a soft partition.

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 adsorption and condensation?
Adsorption is the process by which molecules of a substance adhere to the surface of another substance, while condensation is the phase transition from gas to liquid when molecules lose energy and come together to form a liquid. Adsorption involves surface attraction, whereas condensation involves a change in physical state.
Does physical adsorption have a low adsorption enthalpy?
Yes, physical adsorption typically has a low adsorption enthalpy due to weak van der Waals forces between the adsorbate and adsorbent. These interactions are reversible and non-specific, leading to lower enthalpies compared to chemical adsorption.
What is difference between HPLC and TLC?
HPLC (High Performance Liquid Chromatography) is a technique that separates and analyzes compounds based on their differential interaction with a liquid mobile phase and a solid stationary phase, while TLC (Thin Layer Chromatography) is a technique that separates and analyzes compounds based on their differential movement over a thin layer of adsorbent coated on a solid support. HPLC is more precise and quantitative compared to TLC, which is generally used for qualitative analysis and quick separations.
What is the difference between the Freundlich BET and Langmuir adsorption isotherms?
The Freundlich isotherm describes multilayer adsorption onto a heterogeneous surface with non-specific interactions, while the Langmuir isotherm describes monolayer adsorption onto a homogeneous surface with specific interactions. Freundlich assumes a continuous distribution of energies for adsorption, whereas Langmuir assumes a finite number of identical sites for adsorption.
