Toxic Trace Metals

Toxic Trace Metals

Over the last centuries a considerable increase of toxic elements such as arsenic, cadmium, lead and mercury in the environment has been observed. Human activities and industrialization in particular have contributed to significant release of these naturally occurring elements, hence leading to an accumulation in the food chain. These elements can have adverse effects on organisms and lead to severe illnesses, organ malfunction and even death.

Analytik Jena offers diverse versatile techniques for the determination of toxic trace metals, allowing a reliable risk assessment and quality monitoring for food products.

Speciation of Arsenic in Rice by LC-ICP-MS on PlasmaQuant® MS Elite

Speciation of Arsenic in Rice by LC-ICP-MS on PlasmaQuant® MS Elite

Rice typically contains a high proportion of the highly toxic inorganic forms of arsenic, emphasizing the importance of arsenic speciation in the analysis of rice samples. The combination of excellent chromatography and the high sensitivity of the PlasmaQuant® MS Elite allows for sub parts per billion (<1 µg/kg) limits of detection for all measured arsenic species.

Speciation of Arsenic in Apple Juice by LC-ICP-MS on PlasmaQuant® MS Elite

Speciation of Arsenic in Apple Juice by LC-ICP-MS on PlasmaQuant® MS Elite

Fruits can be highly polluted with arsenic today, due to the use of arsenic-based pesticides during the past century. The different physico-chemical forms of arsenic vary in terms of their mobility, toxicity and bioavailability and reporting only the total concentration can be misleading. The following experiment shows the sensitivity and detection capabilities of the PlasmaQuant® MS Elite for arsenic speciation in apple juice.

Analysis of Heavy Metals in Alcoholic Beverages by HR ICP-OES

Analysis of Heavy Metals in Alcoholic Beverages by HR ICP-OES

Alcoholic beverages are subject to strict quality control due to both health and tax implications. Beside methanol contents that are very harmful to consumers, it is elevated levels of toxic heavy elements like Arsenic, Cadmium and Lead that are often found in bootleg liquors. A commercial whisky sample was submitted to proof of principle analysis of toxic heavy metals.

Impurity Analysis of Zinc Oxides Materials for Animal Feed by HR ICP-OES

Impurity Analysis of Zinc Oxides Materials for Animal Feed and Pharmaceuticals by HR ICP-OES

Hundreds of megatons of Zinc oxide are produced industrially every year, as the white metal oxide powder is used in numerous materials. For three Zinc oxides materials used in animal feed, as ceramic additive and as pharmaceutical precursor toxic impurities (Cd and Pb) and major constituents (including Cu, Fe, Mn, S) were determined.
