Description
This NMKL method describes determination of tin in foodstuffs and canned foods by flame or graphite furnace atomic absorption spectrometry (AAS) after pressurized digestion. The method is applicable to the determination of tin using flame AAS from about 5 mg Sn/kg and from about 0.1 mg Sn/kg by graphite furnace AAS. In 2006, the method was collaborative studied using flame and graphite AAS, respectively, on carrot puree, tomato puree, pineapple, mixed fruit and powder of peach, tomato, beans, fruit yoghurt and white wine. For flame AAS (FAAS) the samples varied from 43 to 260 mg tin/kg. For graphite furnace AAS (GFAAS) the samples varied from 2.5 to 269 mg tin/kg.
