Tin (Sn). Determination in foods by flame or graphite furnace atomic absorption spectrometry (AAS). (NMKL 190, 2009)
This NMKL method describes determination of tin in
foodstuffs and canned foods by flame or graphite furnace
atomic absorption spectrometry (AAS) after pressurized
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.
