NecLife Quality Control Analyst Interview Questions and Answers

Q1. Difference between GC and HPLC
Ans. 
GC is used for volatile compounds, while HPLC is used for non-volatile compounds.
• GC stands for Gas Chromatography, while HPLC stands for High Performance Liquid Chromatography.

• GC is used for separating and analyzing volatile compounds, such as gases and liquids that can be vaporized without decomposition.

• HPLC is used for separating and analyzing non-volatile compounds, such as pharmaceuticals, proteins, and carbohydrat...read more
