|Determination of Veterinary Drug Residues in Milk by GC/MS and GC/ECD|
Yu Chongtian, Lv Jianxia
Purpose: Develop a rapid, sensitive method for determining amitraz and its metabolites in milk.
Methods: Samples were hydrolyzed in acidic condition and extracted with hexane. After derivativation, the samples were analyzed by GC-ECD or directly by GC-MS.
Results: The results show that GC-MS determination of amitraz and its metabolites is rapid and sensitive.
|AUTOMATED WORKFLOW FOR THE DETERMINATION OF FATTY ACID METHYL ESTERS (FAME)|
Beat Schilling1, Reto Bolliger2, Guenter Boehm2
Transesterification of fatty acid esters with Na-methoxide is a fast, efficient and very robust method for fat analysis in food samples. With the use of three ISs the completeness of the transesterification as well as the extent of undesired saponification can be checked.
The PALworkstation allows to fully automate the FAME preparation, including injection into the GC.
|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|

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).
