Toxic metals (arsenic, lead, cadmium, etc.) in foods must be controlled down to low concentration levels. Shimadzu atomic absorption spectrophotometers and ICP emission spectrometers offer highly sensitive analysis of trace elements in foods. Shimadzu’s product lineup also includes X-ray fluorescence spectrometers that can perform elemental analysis without sample pretreatment. These instruments are ideal for screening analysis and emergency analysis.
Shown here is an analysis of cadmium (Cd) and lead (Pb) in α-cyclodextrin (cyclic oligosaccharide), a substance used in functional foods, pharmaceuticals, cosmetics, etc. The analysis was conducted by the AA-7000 atomic absorption

Formula milk powder is formulated to contain a good balance of minerals necessary for infant growth.
Regulations and guidelines in each country include stipulations on the essential mineral content, including calcium (Ca), iron (Fe), and copper (Cu), of food for special dietary use (e.g., formulated milk powder for infants) and requires the labeling. This is an example of simultaneous analysis of elements present in formula milk powder (certified reference material [NMIJ CRM]) using ICP-MS.
