Question

A GC separation of the two compounds shown above (question 3)) is performed at a GC column temperature of 100 °C. The resulting chromatogram shows only one peak. Would the GC separation potentially be better if you were to run another GC at a higher temperature? Please explain.

Answer 1

Answer:

• By and large gas chromatography is altogether influenced by temperature.

• In the event that the temperature is high, at that point the ideal opportunity for association of gas stage with stationary stage is extremely low and partition by adsorption is troublesome and in other hand in the event that temperature is exceptionally low, at that point the connections of the considerable number of segments are high and all adsorbed on stationary stage extremely near one another and detachment become troublesome .

• so in the two cases chromatography isn't appropriate for detachment of segments and because of this reason temperature ought to be progress among buildup and vaporization or kept up 40-50 degree lower than breaking point.

• In the event that if there is temperature low, at that point increment in temperature improves the partition quality however on the off chance that if the temperature is high and breaking point isn't exceptionally high then the expansion in temperature lessen the detachment.
