Hello everyone,
for my first time I'm performing the phtalate analysis, by ALS GC-MS Agilent.
I have followed the Agilent's Application Note 5991-3330, where I have worked in SIM mode. Now I have made a calibration batch by software "MS Quantitative Analysis", and I have some problems of with the calibration curves:
The first five compounds (DIBP-DBP-BBP-DEHP-DNOP) the calibration is okay, good integration of the peaks and good linearity; instead the last two compounds (DINP and DIDP) I have some difficults to integrate and got a good linearity.
Do you have any suggestion??
