ICP - Single element standards
QC working standards may be made up by the analyst from single element solutions. The PrimAg®-xtra certification (for stock 1000 ppm and 10,000 ppm solutions) provides concentration infomation on background elements enabling the analyst to apply corrections where necessary and thereby improve the measurement uncertainty.
Single element standards are available in three certified qualities, from 100ml up to 1 litre:
- PrimAg-xtra, certified, with impurity data
- PrimAg-plus, certified for nominal constituent only, no impurity data provided
- PrimAg-lite, non-certified, intended as QC working reference material only
