Reyhan Selin Uysala, Tümay Temiza, Ismail Hakki Boyacia,b, Hasan Murat Veliogluc, Ugur Tamerd
Discrimination of meat species and meat products was performed with using Raman spectroscopy and principal component analysis (PCA).
|A Mass Spectrometer for Elemental Analysis based on Fieldable Technologies|
Hilary Brown, Jennifer Speer, John Gerling, and Kenyon Evans-Nguyen
Laser ablation and a Microwave Plasma Torch (MPT) were coupled in order to obtain elemental information from solid samples. The MPT was incorporated as a less costly and more portable alternative to the ICP. MPT was also added to help improve the signal from just the laser ablation alone.
|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.
|Microfluidic analysis of amino acids using aminoacyl-tRNA synthetase coupled with spectrophotometric detection|
Analyses of free amino acids in biological fluids?—?such as urine and plasma?—?can be useful in determining disease status in clinical diagnoses . In the food industry, unique changes in amino acid concentrations are useful markers of freshness, nutrition, and taste.
|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.
|Magnetohydrodynamic Based Circular Liquid Chromatography On Chip|
Champak Das Guochun Wang and Forrest Payne
This poster demonstrates cyclic liquid chromatography on chip and shows how this can be used in other closed loop applications.
