Can anyone help me to find a method by which I can measure the concentration of caffeine?
I want to provide an experiment by measuring the concentration of coffee in 3 different ways of preparing the coffee.(filter, instant, cooked coffee). I know for spectrophotometry and liquid chromatography but these methods are not available to me. Is there any other method?
