I successfully prepared stock solution of the right concentration. However, after dilution of stock solution to lower concentrations, such as from 5000 ppb to 500, 300, 200, 100, and 10 ppb, I was unable to get the correct responses/concentrations after being analyzed using GC for my standards of lower concentrations.
What problems that I may have that leads to these inaccuracies?
Thanks!
