wt is difference between assay and purity in hplc?

Answer Posted / jay jadhav

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.

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
