Homework Answers
In gc when the two compunds that are being seperated have very similar retention time then we have to increase the retention time son that we get better seperation
Always remember in both gc and hplc the longer the run time better will the seperation and shorter the run time the seperation is poorer
So in order to increase the run time and get better resolution and seperation the following changes should be done
01. Pressure - the pressure should be lowered
Increased pressure means short run time and poor resolution and seperation
02. Heating ramp rate -
The heating ramp rate should also be lowered so we get better seperation
03. Length of column
- longer the length of column better will be the seperation
I hope this helps. If you have any query or want more detailed explanation, feel free to ask in the comments section below.
