What is post run in hplc?
Answer / satheesh kumar
Post run in hplc comes under the gradient programme
(Gradient elution).
Gradient Programme-:
Time(min) A% B%(Where-A% Buffer,B%-ACN)
0.01 80 20
10.00 50 50
25.00 20 80
30.00 20 80
35.00 80 20
45.00 80 20
In the above gradient Intially starts with Buffer,ACN in
one proportion,when the time incerases proportion changed
and finallty returns to original proportion is called Post
run or equilibrqtion time
