Solution Prep

To prepare a ninhydrin solution, use a 0.5% alcoholic solution. Add 0.5 g of ninhydrin to 75 ml of n-butyl alcohol or ethyl alcohol or isopropyl alcohol. Heat gently until all the solid is dissolved. Alcohols are a fire risk, so be careful. Dilute to a final volume of 100 ml with the chosen alcohol.
