Analysis Note

The purity is calculated based on the principle of mass balance and is mentioned on the CoA

Other Notes

Ion Mobility: TWCCSN2 value of 160 Å2 [M+H]+ and 179.6 Å2 [M+Na]+

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.

P/N 08902 is part of the Waters Extractables & Leachables UNIFI scientific library which can be downloaded from Waters Marketplace.
