Does anyone build a calibration curve with 0 as a calibrator? We're transitioning from using Chemstation to MassHunter Quantitative Analysis for our GCMS data. For Chemstation, we have a 7 points calibration curve with level 1 being a 0 calibrator. However, when using MassHunter, we cannot get MassHunter to count the 0 calibrator as a level unless it integrates something from it. Is there a way to go around this without making it a 6 points calibration curve with level 1 being the lowest calibrator?
