AN355: Rapid Extraction and Determination of Arsenicals in Fish Tissue and Plant Material Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

The toxicity of arsenic is species dependent. Inorganic arsenic species such as arsenite (As[III]) and arsenate (As[V]) have been classified as carcinogens. Methylated forms such as monomethylarsonic acid (MMA) and dimethylarsinic acid (DMA) have recently been labeled as cancer promoters. Arsenobetaine (AsB), arsenocholine (AsC), and arseno sugars have been found to be relatively nontoxic. This application note describes ASE methods for the extraction of various arsenic species from different food matrices, specifically fish tissue, ribbon kelp, and vegetables grown in contaminated soil.

Improved analysis of carotenoids and chlorophylls in vegetables using a Thermo Scientific Acclaim C30 column

Instrument Type: HPLC

The Thermo Scientific Dionex UltiMate 3000 RS system is applied for the analysis of carotenoids and chlorophylls. The separation was performed in less than 25 minutes on a Thermo Scientific Acclaim C30 column with UV detection.
