A portion of the reconstituted sample residue was injected onto a YMC Basic analytical column which was connected to a triple quad mass spectrometer for analyte determination by positive-ion electrospray in the selected reaction monitoring (SRM) mode.
Mass spectra quantified on GC 7890A series equipped with MS 7000 GC/MS triple quad using DB-5 silica capillary column (30 m × 0.25 mm I.D).
Nicotine quantification by ultra high performance liquid chromatography triple quad mass spectrometry (UPLC-MS/MS) was based on published methods [20, 33].
Analytes were separated and detected using an AB Sciex (Framingham, MA, USA) API 3000 triple quad LC MS/MS system with positive electrospray ionization (ESI) and operated in multiple reaction mode.
The Shimadzu LCMS 8030 triple quad instrument was used with the following settings: 1.5 L/min nebulizing gas flow, 250 °C DL temperature; 400 °C heat block temperature; 15 L/min drying gas flow).
Rachelle Simpson, of San Antonio, Texas, won the women's division and the UK's Gary Hunt dominated the men's division with a triple quad (three somersaults and four twists) that earned him a bunch of 9s from the judges.
