Equipment
Two triple quadrupole mass spectrometers coupled to a UPLC can be used:The first LC-MSMS system consists of a UPLC (Accela®, Thermo Scientific, San Jose, CA, USA), a quaternary ultra high pressure pump, a vacuum degasser and an autosampler, coupled to a (TSQ Vantage®, Thermo Scientific, San Jose, CA, USA) triple quadrupole mass spectrometer.
The second LC-MSMS system consists of a UPLC (Acquity® I-Class, Waters, Milford, MA, USA), a binary ultra high pressure pump, a vacuum degasser and an autosampler, coupled to a (TQ-S micro®, Waters, Milford, MA, USA) triple quadrupole mass spectrometer.
