Disadvantages & Advantages of an GC

Submitted by frndzzz on Sat, 06/28/2014 - 14:14

Disadvantages & Advantages of an GC.

Gas chromatography (GC) is an analytical method which is used for the separation of an volatile substance from a give mixture of compounds which are very difficult to separate and analyse.

This type of chromatography separates the molecules based on the volatility of a substance.

The substance with more volatility will separate out quickly while the substance with less volatility will elute out slowly.

Advantages 

This method has a  high resolution power compared to other methods.

This method has high sensitivity when used with thermal detectors.

This technique gives relatively good accuracy and precision.

Separation and analysis of sample very quickly.

Sample with less quantity is also separated. 

Disadvantages

Only volatile samples or the sample which can be made volatile are separated by this method.

During injection of the gaseous sample  proper attention is required.

The sample of gas which is about to inject must be thermally stable so that it does not get degraded when heated.

Advantages and disadvantages of Chromatography

Submitted by frndzzz on Sat, 06/28/2014 - 17:12

Chromatography is simple method. Chromatography can be handled by single person.

Other advantages are, Chromatography is used to separate components from complex mixture.

Different types of chromatography equipment are available for separation of different compounds.

Some of them are Gas Chromatography, Liquid Chromatography, Solid Chromatography, High performance liquid Chromatography, Solid liquid Chromatography, Liquid liquid Chromatography, Thin layer Chromatography. This method gives accurate results.

Some Disadvantages & Advantages of an TLC.

In Thin layer Chromatography also called (TLC) is widely used method for the separation and detection of an molecule from a given mixture of compounds.

This method is used for the separation of non volatile compounds.

This is generally performed on the thin sheet of aluminum or thin sheet of glass or plastic.

This sheet are coated with different media, commonly used are silica gel, cellulose etc.

The sample is applied on this plate and it is called stationary phase.

There are various different types of chromatography which are used today in different industries and in day to day life.

Before going into detail let us check it out the definition of the chromatography.

The chromatogaphy is the separation of a component from of complex mixture of substance.

Types of component, functional group or structure can be identified with the help of chromatography.

List of some of the equipment are as follows:

Gas chromatography

Liquid chromatography

Solid chromatography

Liquid-liquid chromatography

HPLC - High Performance Liquid Chromatograpy

The term high performance liquid chromatography, also known as HPLC.

Other related forms which are used today are liquid chromatography, gas chromatogaphy, solid liquid chromatography.

column chromatography, solid-liquid chromatography, liquid liquid chromatography and much more.

Which are used for the separation and identification of an unknown component from a mixture of molecule.
