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.
