LC/MS/MS Quantitation of Eicosapentaenoic Acid in Rat Plasma
Rachel Sun, Jordan Nally, Tim Shoaf

Eicosapentaenoic acid (EPA) is an omega-3 fatty acid, which has been documented to be important in biochemical and physiological processes including inflammatory response, blood clotting and the immune system. Eicosapentaenoic acid (EPA) appears in different forms in the blood including triglyceride, ethyl ester, or free acid. In this work we presented an LC/MS/MS method to quantitate the total eicosapentaenoic acid in rat plasma with a 96-well plate format.

Ion Chromatography ICP-Q-MS for the Detection of Arsenic Species in Apple Juice
Daniel Kutscher, Shona McSheehy-Ducos, Julian Wills and Detlef Jensen

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.

Characterizing Small Molecules in Biological Extracts using IntelliXtract Data Processing on High Resolution Accurate Mass Time-of-Flight Data
Margaret Antler, Graham A. McGibbon, Vitaly Lashin, Jeffrey S. Patick and Kevin Siek

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.

The LAB2LAB™Advantage
Dr Brian Everatt1 C.Chem., FRSC, Simon Tullett2

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.

Analysis of Pesticide Residues in JonaGold Apples Using QuEChERS Approach and Comprehensive Two-Dimensional Gas Chromatography Time-of-Flight Mass Spectrometry (GCxGC-TOFMS)
Joe Binkley, John R Heim and Doug Staples

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.
