Working out quinine ppm in tonic water?

02 February 2019 1 3K Report

Hi,

I made some tonic syrup and then ran hplc analysis. I tried to work out the concentration of quinine in the syrup, by using the linear equation from the calibration curve for a quinine standard I made. Then I worked out the mass per g of quinine in the bark.

The recipe for tonic water I followed takes 21ml of syrup and combines it with 96ml of water, so I need to know the quinine ppm in the tonic water, but I am not sure how to do this. Any help is greatly appreciated.

Do you know anything about the quinine concentration in the original syrup?
