there is no difference between high pressure and performance chromatography
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).

Flash chromatography uses pressure (under 10 psi) to pump solvent down a column at a rate faster than gravity would provide. Vacuum chromatography uses a vacuum at the bottom of the column to pull solvent through. Both can be performed with standard glass columns, but usually vacuum chromatography is done with a silica filled vacuum funnel instead as a rough purification technique.
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.
Flowing air responds to the difference in pressure between higher and lower pressure areas by moving from high pressure to low pressure to equalize the pressure. This movement of air creates wind, which is the result of the pressure difference seeking equilibrium.

Anion exchange chromatography separates molecules based on their negative charge, while cation exchange chromatography separates molecules based on their positive charge.
Cation exchange chromatography separates molecules based on their positive charge, while anion exchange chromatography separates molecules based on their negative charge.

Anion exchange chromatography and cation exchange chromatography are both types of ion exchange chromatography used to separate molecules based on their charge. The key difference between them is the type of ions they attract and retain. Anion exchange chromatography attracts and retains negatively charged ions (anions), while cation exchange chromatography attracts and retains positively charged ions (cations).
what is the difference between thrust and pressure?

Cation exchange chromatography separates molecules based on their positive charge, while anion exchange chromatography separates molecules based on their negative charge. The key difference lies in the type of charge that is used to separate the molecules.
Differential pressure is the difference in pressure between two points in a fluid system, while static pressure is the pressure at a single point in the system.
The pressure difference formula is P gh, where P is the pressure difference, is the density of the fluid, g is the acceleration due to gravity, and h is the height difference between the two points. To calculate the pressure difference between two points, you can use this formula by plugging in the values for the density of the fluid, acceleration due to gravity, and the height difference between the two points.
