What is the function of suppressor column in HPLC?
As far as I'm aware, suppressor columns are primarily used in ion chromatography just. They remove strong ions (ie replace Na+ with H+) allowing for a decrease in background detection (due to the eluent). A link is provided to the process that goes on in a suppressor for IC made by metrohm
What are the differences between column chromatography and sublimation in terms of their principles and applications?
Column chromatography separates compounds based on their different affinities for a stationary phase, while sublimation separates compounds based on differences in their volatility. Column chromatography is commonly used in purifying mixtures of compounds, while sublimation is often used to purify solids that can sublime.
Role of Ion suppressor in ion chromatography?
The suppressor reduces the background conductivity of the chemicals used to elute samples from the ion-exchange column. This improves the conductivity measurement of the ions being tested. check it http://www.dionex.com/en-us/products/accessories/suppressors/lp-73569.html
What is the first substance to elute in column chromatography?
The first substance to elute in column chromatography is typically the one that interacts the least with the stationary phase and moves through the column the fastest.
What is the elution order of compounds in column chromatography?
In column chromatography, compounds elute in order of increasing polarity. This means that less polar compounds will elute first, followed by more polar compounds.

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.

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.

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 first substance to elute in column chromatography?
The first substance to elute in column chromatography is typically the one that interacts the least with the stationary phase and moves through the column the fastest.
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).
Are Adsorption and partition chromatography types of column chromatography?
Yes,both can performed in columns.
What is difference between column and piller?
Do you mean the difference between column and PILLAR?Column is the supporting pillar while pillar is a n ornamental column. Thus, pillar is a decorative while column provides the actual support.
