Benefits of FTIR Spectroscopy

The Advantages of FTIR Spectroscopy. Method offers high-speed and sensitivity compared to earlier dispersive  methods of IR (Infrared spectral) analysis. These advantages are:

Some of the benefits of FTIR Spectroscopy are as follows:

  • Liquids , solids as well as gases can be analysed by FTIR spectroscopy.
  • It is the non-destructive method.
  • FTIR analysis can be made within seconds , it is faster technique than others.
  • Simultaneous analysis is possible of different gaseous compounds.
  • No external calibration is required.
  • Fellgett advantage
  • Jacqionot advantage

Disadvantages & Advantages of an GC

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 and disadvantages of Chromatography

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.

Disadvantages & Advantages of an TLC

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.
