Chromatography- Part 2-Phyto-1- Class 24/25

Polymers could be analyzed by GC after:

• Outgasing

• solvent extraction

• Pyrolysis

• Solid phase micro extraction

The connective tubes in GC are made of:

• Copper

• Aluminum

• Stainles steel

• Polymer

Caoillary column in GC is characterised by:

• Large sample capacity

• Low resolution

• Great sensitivity

• Long analysis time

One of the GC detectors which detects the components at nanogram level:

• Mass detector

• ECD

• FID

• TCD

GC detector which relies on the fact that electronegative atoms, like halogens, will capture electrons from a β-emitter.

• FID

• ECD

• TCD

• Mass detector

A universal and non-specific GC detector:

• Mass detector

• ECD

• FID

• TCD
