The mass spectrum of the Pierce™ FlexMix™ calibration solution has peaks close to the theoretical values listed in the following tables.
NOTE
The Pierce FlexMix calibration solution is available for purchase from Thermo Fisher Scientific. Go to thermofisher.com and search by the part number.
- Pierce FlexMix calibration solution for Auto-Ready MS's (P/N A51739)
- Pierce FlexMix calibration solution (P/N A39239)
IMPORTANT
If you observe interfering peaks in the spectrum that are within ±10 Da of any of these calibration masses, follow the procedure for flushing the inlet components until the interfering masses show less than 25 percent of the intensity of the calibrant ions.
