Description
This method describes how to quantify tin in foodstuffs and canned foods by inductively coupled plasma mass spectrometry (ICPMS) after pressurized digestion. The lowest validated level in the study was: 2.5 mg/kg. The limit of quantification depends on the amount of sample used for digestion, on the final volume of digestion and on the minimum dilution applied. The ICPMS instrument should be able to quantify 1 μg/L tin in the diluted digestion solution. For the example given in this method, the limit of quantification is 0.4 mg/kg.
