| Other Notes: | Ion Mobility: TWCCSN2 value of 133.2 Å2 [M+H]+ The collision cross section (CCS) measurement was provided by Waters Corporation, using the SYNAPT XS mass spectrometer. For a description and overview of how ion mobility enables the measurement of the CCS of an ion visit ims.waters.com . Further information on the SYNAPT XS mass spectrometer can be found on the IMS microsite and product webpage. TWCCS measurements are expected to be within 2% of this reference value.
