Witrynaan analytical method for these impurities. In this application note, a highly selective Multiple Reaction Monitoring (MRM) based LC/MS/MS method was developed using an Agilent 6470 triple quadrupole LC/MS (LC/TQ). The sensitivity of the 6470 LC/TQ can easily detect compounds at the required limits of detection. The special design of the WitrynaAs Figure 3 shows, the impurity has a 60% higher S/N ratio on the CORTECS C 18 +, 2.7 μm Column compared to the competitor solid-core C 18, 2.6 μm column. A higher S/N ratio gives the analyst a better signal leading to more accurate data analysis and detection of peaks at lower concentrations.
