#Agilent chemstation quantitation database how to

If your low standard gives 100,000 area counts TIC and the surrogate and internal standard only contribute 1000 area counts TIC each then the low standard will only be 2% higher than it should be and keeping these compounds constant throughout the calibration curve would have even less effect on the rest of the standards and you could probably mitigate the 2% on the low calibration through curve weighting. If your surrogate has to elute during the window for your target compounds you could spike it at a very low level so that it still gives a good signal for the target ion but does not contribute enough to the total ion chromatogram of the low standard to effect the overall quantitation or response factor. I quantify the surrogate using the Target ion. Since I was working with external standard calibration I just had to move to using 1-methylnaphthalene which elutes just past the normal end of the gasoline range. I never could figure out how to automatically remove the areas of the internal standard or surrogate so I chose different compounds.

I normally use RTE integrator simply because after using it since before Chemstation was on Windows I still know what all the settings do.
