Simple Distillation and GC

distillation

process of vaporizing a liquid, condensing the vapor, and collecting the condensate in another container

what is required to get good/better seperation?

a larger amount of of theoretical plates

the smaller the gap in boiling points the…

more theoretical plates

the larger the gap in boiling points the…

less theoretical plates

what are the lanes on a TLC plate for distillation?

1. crude mixture

2. simple distillation

3. fractional distillation

stationary phase

silica gel which is very polar so molecules that are polar stick and don’t move

gas chromatography

analytical/preparative method used to separate and analyze compounds that can be vaporized w/out decomposition

in gas chromatography the mobile phase is…

gas

compounds that boil quickly become…

a gas first and move faster through the stationary phase

if compounds come out the column first how is there retention time?

it’s low bc it eluded faster

what does the area under the curve represent in GC?

the compound’s concentration w/in the sample
