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).
Distinguish between TLC and hptlc?
TLC is Thin layer Chromatography while HPTLC is High Performance Thin Layer Chromatography HPTLC is Automotive ,It has Scanner,Injector,Developer -al automated and controleed generally by Software
What is the difference between vacuum chromatography and flash chromatography?
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.
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.
How much does a chromatography cost?
The cost of chromatography equipment can vary widely depending on the type and complexity of the system. Basic bench-top chromatography systems can range from $5,000 to $20,000, while more advanced systems, such as high-performance liquid chromatography (HPLC) or gas chromatography (GC), can cost between $20,000 and $100,000 or more. Additionally, ongoing costs for consumables, maintenance, and software can add to the overall expense.

What is the difference between anion and cation exchange chromatography?
Anion exchange chromatography separates molecules based on their negative charge, while cation exchange chromatography separates molecules based on their positive charge.
What is the difference between cation and anion exchange chromatography?
Cation exchange chromatography separates molecules based on their positive charge, while anion exchange chromatography separates molecules based on their negative charge.

What are the key differences between anion exchange chromatography and cation exchange chromatography?
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 are the key differences between cation exchange chromatography and anion exchange chromatography?
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.
What is the pressure difference formula and how can it be used to calculate the difference in pressure between two points?
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.
What is the difference between differential pressure and static pressure in a fluid system?
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.
What are the differences between column and thin layer chromatography?
In chromatographic terms, TLC has great advantages over the other chromatography modes, such as Liquid Chromatography (LC), Column Chromatography (CC), Gas Chromatography (GC) and High Pressure Liquid Chromatography (HPLC).TLC's advantages are: (1) the ability to perform multiple analyses simultaneously; (2) speed and ease for scouting separation conditions, such as optimum solvent mixtures.
