Assay is the quantitative determination of the amount of a
component in a sample.
Purity is the determination of the impurities in the
sample. It can be quantitative, semi-quantitative or
qualitative.
For example : if you dissolve 4 grams of compound A (with
no impurities in it) in 6 grams of water, you get a
solution of compound A with 100% purity and 40% assay.
