EPR Spectroscopy as an Alternative Analytical Method for Copper Determination in Alcoholic Beverages

Pages 761-770 | Published online: 18 Feb 2008
 

ABSTRACT

An alternative, highly selective method for cooper(II) analysis in alcoholic beverages (brandies) is proposed using EPR spectroscopy. The method is simple, non destructive, fast and can be used for concentrations down to 100 ppb, with 1.1% (x = 1.55, s = 0.0179) RSD (relative standard deviation) and 98.7% accuracy.
