Detectors for Column Chromatography

[ggxoxo]

Hi; I was just really confused about the Flame-Ionisation Detectors in GC? How does it work?

And also: GC is a type of column chromatography, right? (just want to make sure  )

Thanks!!!

On leaving the coloumn, the sample is burned in a H2-O2 flame to produce ions. The ions produced are attracted to an electrode and cause a current to flow. The intensity or size of the current produced as the result of the ion flow is recorded as a series of peaks. The time taken for each peak to appear is calculated (the retention time). Note, the flame ionisation detector destroys the materials being tested. If the components being seperated need to be collected for further testing, a different detector would need to be used.

Yeah I think GC is a type of column chromatograpy. Can someone please confirm?

Hope that helps!!
