Rapid Identification of Microorganisms by Touch Spray and Paper Spray Ambient Ionization
Ahmed M. Hamid, Alan K. Jarmusch, Valentina Pirro and R. Graham Cooks

The rapid and accurate identification of microorganisms is necessary in order to improve public health. Molecular-based identification allows for rapid patient treatment and provides more accurate diagnoses, two crucial aspects for successful treatment, yet a great challenge. In this work PS-MS, an existing ambient method, and TS-MS, a newly developed technique, are being utilized in the rapid discrimination of microorganisms (<2 min).

Fingerprinting analytical strategy used for authentication of honey
Oana Romina DINCAa,b, Roxana Elena IONETEa*, Raluca POPESCUa, Radu TAMAIANa, Diana COSTINELa, Gabriel Lucian RADUb

The goal of the current study is mainly to establish potential origin markers, and not to build a model for prediction. This research provides a database for comparison of honey samples from Romania with other honey samples from the world. Data on d13C, d18O and d2H of honey measured by IRMS together with the stable isotopes (deuterium by SNIF-NMR and carbon 13 - IRMS) in ethanol from fermented honeys were reported.

Determination of Metabolically Unstable Drugs in Blood by Heat-Stabilized DBS and LC-MS/MS

The aims of this work were to investigate drug stability prior to, during and after blood spot sampling, using procaine, prulofloxacine, esmolol, and acetylsalisylic acid as examples of drug compounds with limited stability and to compare conventional DBS sampling procedure with DBS sampling including heat stabilization.

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.
