What are the advantages and the disadvantages of HPLC?

What are the advantages and disadvantages of HPLC as a technique for the separation of proteins and peptides? The SCX/HPLC technique has been widely used with highly complex peptide mixtures. The advantages of this technique include minimal sample handling, ease of use, and automation.

What does HPLC stand for?

1. What is HPLC? What does it stand for? HPLC (stands for High-Performance Liquid Chromatography) is an analytical technique commonly practiced in the pharmaceutical industry to separate, identify, and quantify components in a mixture – when these compounds are non-volatile, thermally unstable, and possesses relatively high molecular weights.

Why is HPLC used?

High-performance liquid chromatography (HPLC) is a chromatographic technique used to split a mixture of compounds in the fields of analytical chemistry, biochemistry and industrial. The main purposes for using HPLC are for identifying, quantifying and purifying the individual components of the mixture.
