Dangerous Heavy Metals in Food: Fast Determination of Cd, Pb and As in Rice
9 Jan 2012
Wheat and Rice take up relatively more heavy metals from soil than other grains so fast, simple yet thorough analysis is essential to maintain safe standards. This application note from Analytik Jena presents a direct solid sampling technique for Graphite Furnace AAS which fulfils these requirements. Sample preparation can be almost completely omitted, it is sufficient to just take a representative sample and homogenize it in a ball mill.
