Strontium Interference on Calcium
Issue
Recovery of quality control and unknown samples could be excessively low when strontium-88 and calcium-44 are used during calibration.
Environment
- iCAP Q
- iCAP RQ
- iCAP TQ
- ECCN:EAR99
Resolution
If it is necessary to analyze calcium at a mass/charge of 44, then an interference equation can be calculated by determining the strontium overlap onto calcium using a single element strontium standard.
Cause
Isobaric overlap of double charge strontium-88 with calcium-44
