quantifying multiple graphic groups and area objects on SCD

Post by BSpear » May 11th, 2017, 12:55 pm

On SCD detector analysis you would typically use one or two internal standards and assign the same response to many blobs, area objects or graphic groups. How can this be done in GC Image? Is it possible to use multiple internal standards?

The calibration procedure is as same as without a group. For quantification, Configure > Calibration Table and set
  • Calibration Options > Compute amounts for to All
  • Calibration Options > Extrapolation to Fit Line
More details can be found from Help > User's Guide > Quantification:
  • Quantifying Uncalibrated Compounds
  • Quantifying Compound Groups
And, it is possible to use multiple internal standards pairing with different targeted compounds.
