چکیده

We discovered novel calibrants, several 2,2,6,6-tetraalkylpiperidinyl derivatives, for accurate mass measurements by electrospray ionization mass spectrometry (ESI). These compounds showed excellent performance as internal calibrants for the accurate mass measurement in ESI-MS, without problems arising from differences in the ionization efficiencies between the analytes and calibrants.

Evaluation of Collision Cross Section Calibrants for Structural Analysis of Lipids by Traveling Wave Ion Mobility-Mass Spectrometry

Collision cross section (CCS) measurement of lipids using traveling wave ion mobility-mass spectrometry (TWIM-MS) is of high interest to the lipidomics field. However, currently available calibrants for CCS measurement using TWIM are predominantly peptides that display quite different physical properties and gas-phase conformations from lipids, which could lead to large CCS calibration errors f...
