For an analytical application, I wouldn't try to do it that way. First of all, we should try to understand the drift: random, or rising or falling? All three have different explanations possible. What happens if you leave the instrument powered for a long time? Drift may stop if you do. Perhaps the instrument specifies a warmup time, 15 minutes or an hour. And perhaps you discover that it needs more -- that happens.
If the drift is linear, then you can develop a curve for standards that flank your samples. If your drift is random, then the average of your standards may be the best answer you can get.
But a lot of this is outside of how most people like to report their analytical results. You should give us some information on your application.
