Answer 1

The Advantages of Chromatography are:-

1. Precise separation, analyses, and

purification is possible using

chromatography.

2. It requires very low sample volumes.

3. It works on a wide range of samples

including drugs, food particles, plastics,

pesticides, air and water samples, and

tissue extracts.

What is the advantage of using Chromatography?

Want to get more out of Visual Studio?

Chromatography is one of the most versatile techniques available to a chemist (the other one being spectroscopy.) If you understand the principles of both of these techniques, you covered about 80% of standard lab instruments.

Chromatography is used for a large range of applications. It’s mainly used to separate complex mixtures. You can separate compounds based on their size, molecular weight, ionic mobility, polarity, boiling point etc. This allows us to measure the concentration of a specific compound in a mixture. Because of this, it is a widely used technique.

There are instruments that combine both chromatography and spectroscopy (GCMS, LCMS etc.) They are used from analyzing unknowns, drug testing to many others. You only inject couple of microliters into the instrument. So while it’s a destructive method (you cannot recover the sample), the generated waste is minimal.

So the advantage of using chromatography is mainly its versatility. Electro chemistry has been catching up with these techniques specially with the miniaturization of electrodes. It has the potential to become a very useful technique as well (it already is but there’s always room for improvement.) While chromatography is very useful, standard instrument is pretty big and you cannot carry it into the field. So techniques like cyclic voltammetry may be the solution for that. Each has their strong and weak points. You need to be familiar with an array of techniques and instruments to fully function in the field of chemistry.
