Abstract

An improved ion-exchange resin method to detect low levels of dye marker Brilliant Blue F.C.F. (C.I. No. 42090) in milk was developed. Sensitivity of 0.02 mg of dye per liter (corresponding to 0.008 I.U. of penicillin per milliliter), and semi-quantitative adaptation of the method is described.
