I am using v/v % to express concentration of my analytes in solution. I am adding 40uL of 16 different analytes (purity ranges from 95% to 99,9% with average of 99,2%) and diluting a solution to 800uL with acetonitril.
So, calculation is v/v % (per analyte) = 40uL x 99,2% / 800uL = 4,96%
How to calculate a concentration of each analyte if I took 40 uL from 4,96% solution and diluted it to 800uL with acetonitrile again.
Is it again: v/v % (per analyte) = 40 uL x 4,96% / 800 uL = 0,284%? Am I doing something wrong?
