|GC-MS Comparison of Lavindin Grosso Oil Obtained by Steam Distillation and SFE|
Claudia Worley, Lisa Zona, Susan Sonchik Marine
Oil was extracted from Lavindin Grosso using steam distillation and using supercritical fluid extraction (SFE). Multiple analyses of the same extract demonstrated repeatability of the analytical method. The variability between batches of distillate bracketed the composition obtained by SFE. The differences among the oils could be attributed more to where the lavender was grown than to the extraction method.
|Purification of Synthetic Oligodeoxynucleotides via Catching by Polymerization|
Suntara Fueangfung, Shiyue Fang
This poster describes new simple methods for oligodeoxynucleotide purification without chromotography.
|Chemometrical optimization and fast determination of debittering of table olives by means of capillary electrophoresis|
Albillos SM, Busto MC, Ortega N, Pilar-Izquierdo MC, Ramos-Gómez S, Pérez-Mateos M
Table olives require a thorough process of debittering in order to achieve the organoleptic quality of olives before consumption. Capillary electrophoresis offers several advantages to the determination of the bitter responsible compound oleuropein in table olives, such as speed, reduced amount of solvents and reagents, small amount of sample, high efficiency and lower costs.
|Identification and classification of antifouling compounds secreted by anti MIC microorganisms. A metabolomic analysis.|
Albillos SM; Balaña-Fouce R; Montero O; Barreiro-Mendez C; Blas-Galindo E; Barros-García R; Guedella-Bustamante E; Ullán RV
BIOCORIN project, aims to develop a green alternative to the coatings and solutions used up to date for MIC corrosion control. Some of the results of this project are presented here, with the identification of several relevant antifouling compounds secreted by environmentally isolated anti-MIC strains of microorganisms via a metabolomic approach.
|Discrimination of Meat Species Using Raman Spectroscopy and PCA|

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.
