Interest in the determination of Arsenic species in fruit juices has been triggered by recent media reports in the United States claiming that some apple juices may contain high amounts of Arsenic. Inorganic forms of Arsenic (As3+ and As5+) are highly toxic, whereas the organic forms (e.g. arsenobetaine) are not considered toxic. A robust IC-ICP-MS system was developed and shown to be a highly selective and sensitive technique for determination of trace element species.

To detect small molecules in biological extracts, LC/MS performed using high resolution time of flight with accurate mass analysis is a powerful technology. Together with advanced data processing algorithms, accurate mass and relative isotope abundance measurements, molecular formulae can be determined and compounds identified.

ACD/Labs has been developing specialized software for chemical and pharmaceutical research for over 16 years. Their expertise includes multi-technique, multi-instrument data handling, knowledge management of analytical and separations data, chemical drawing, and prediction software for a range of chemical properties as well as spectra and chromatograms.

Lab2Lab is a novel approach to submitting and transporting samples for analysis across an entire site. Sample tubes are registered and methods selected, an ELN reference is assigned and the sample tube is placed into the “Sender”. The system transports the samples using low pressure compressed air and directs them to the most appropriate analytical instrumentation available. The analytical results are then automatically returned to the originators ELN.

The evaluation, identification, and quantitation of flavones, antioxidants and related nutrients, biogenic amines, and potential contaminants in wine and other foodstuffs provides valuable information on their nutritional and health values.

Screening and quantitation of pesticide residues in fruits and vegetables is of utmost importance for public health and safety concerns. These commodities can contain hundreds-to-thousands of analytes, making them extremely difficult for the screening and accurate quantitation of pesticide residues.

The availability of fruit commodities from a wide variety of sources has increased the need for rapid and accurate screening for pesticides in fruit. Not all fruit commodities are brought to market under the strict guidelines of the United States Department of Agriculture. Determining whether or not the Environmental Protection Agency tolerances for various pesticides have been violated is important in the risk assessment for consumers in the United States.

The qualitative and quantitative analysis of the content of nutritional supplements and alternative medicinal therapies is becoming more important and regulation by the FDA is imminent. High resolution mass spectrometry provides a rapid, selective, and useful mechanism for QC of extracts and finished dosage forms, producing a minable, comprehensive data set.

Dispersants are plasticizers commonly used to prevent clumping and help dissipate oil slicks. In this work, we used GC/MS and LC-MS/ MS to detect and indentify two of the most widely used dispersants (Corexit 9527 and 9500).

Lexicon Pharmaceuticals have demonstrated that a practical automated verification system using HPLC, LC/MS, and 1D and 2D NMR can be implemented in an industrial/pharmaceutical environment. This system has proven to be robust, and provides added value to compound collection integrity and quality.
