HPLC stands for High Performance Liquid Chromatography, a technique used to separate, identify, and quantify components in a mixture.

• HPLC involves a stationary phase, a mobile phase, and a detector to separate and analyze compounds based on their interactions with the phases.

• It is commonly used in pharmaceutical, environmental, and food industries for quality control and research purposes.

• HPLC can be used to analyze co...read more

A GC stands for Gas Chromatography, a technique used to separate and analyze compounds in a mixture.

• A GC involves injecting a sample into a column where it is vaporized and carried by an inert gas.

• Compounds in the sample interact differently with the column material, causing them to separate based on their properties.

• The separated compounds are detected by a detector and can be identified based on their retention time
