Purity as a documentation value
Percent purity is commonly converted to a fraction for records. For example, 98% becomes 0.98.
Formula explanation
Theoretical pure-material equivalent equals measured mass multiplied by the purity fraction.
Research documentation example
A measured 10 mg record at 98% purity has a theoretical pure-material equivalent of 9.8 mg.
Common documentation mistakes
- Using 98 instead of 0.98 as the fraction.
- Not labeling the purity source.
- Writing adjusted values without the measured mass.
