1-Gas chromatography (GC)

 Gas chromatography is an instrumental method for the separation and identification of volatile and thermally stable chemical compounds. The process is based on separating mixture of compounds into its individual c...

2-Gas Chromatography–Mass Spectrometry (GC-MS)

 Gas Chromatography–Mass Spectrometry (GC-MS) is a hyphenated analytical technique that combines the separation properties of gas-liquid chromatography with the detection feature of mass spectr...

3-High performance-Liquid chromatography (HPLC):

 It's the most widely used techniques that involves the separation of liquid mixture sample into its individual parts by passing through stationary phase with carrier liquid mobile phase deli...

4-Liquid chromatography-Mass spectrometry (LC-MS):-

It's an analytical technique that combines the physical separation capabilities of liquid chromatography (or HPLC) with the mass analysis capabilities of mass spectrometry (MS). The sample...

5-Atomic absorption spectroscopy (AAS):

Is an analytical technique that measures the concentrations of elements. It makes use of the wavelengths of light specifically absorbed by an element. The atoms absorb ultraviolet or visible light Tha...
