A GC–high‐resolution isotope dilution MS (IDMS) method for the quantification of melamine in milk powder is described. The developed technique is compared to the LC‐IDMS/MS technique, typically used for the determination of melamine in various matrices. The accuracy of the GC–high‐resolution IDMS method was demonstrated when a small degree of equivalence was obtained in a regional comparative study involving the determination of melamine in milk powder.
