This new liquid chromatography-tandem mass spectrometry- quadrupole ion trap (LC-MS/MS-QTRAP) method identifies rat poisons in cat forensic cases.
Ultrahigh throughput is shown for ultrafast gradients with over 60 % reduction of total analysis time using alternating column regeneration. This was accomplished with parallel injection by the second needle installed in the Agilent 1290 Infinity II Multisampler, which has a dual-needle option for the analysis of food preservatives.
