ANALYTICAL TESTING OF THE INTERFERENCE STANDARD METHOD (IFS) FOR METALS IN WINES BY INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY
An analytical testing study of interference standard method (IFS) for metals in wines with low and high residual sugar by inductively coupled plasma mass spectrometry (ICP-MS) was evaluated. Selection of IFS probes was based on the ions formed in the argon plasma, such as natural 38Ar+ or contaminan...
