I'm using openlab cds 2.7. I have 3 componds: aroclors 1242,1254, and 1260. I need to set up a calibration curve for each compound in the same processing method? Example 1242 has 5 peaks that total 50ppm. 1254 has 3 peaks that total 50ppm. 1260 has 5 peaks that total 50ppm. The only issue I have is that i have to run each compound separately and all of the compounds will show up smaller amounts in the other other compound since this is a complex compound. Example 1242 will show up smaller amounts of 1254 in it. 1254 will have some 1242 and 1260 in it. I know in chemstation, I set it up so that you could recalibrate each compound in a single injection. I'm not sure how to do this in openlab cds.
