GC-MS/MS Analysis of Pesticide Residues in Green Tea Extracted by QuEChERS with Acetonitrile as Final Solvent
Cojocariu C., Morgan P., Silcock P., Pelagatti S., Magni P. and Pigozzo F.

This poster describes the analysis of several challenging pesticides from green tea samples using GC-MS/MS and acetonitrile as final extraction solvent. The compounds analysed are representatives of various classes of pesticides, such as carboxamids, OC, OP, pyrethriods, aromatic, phenylamides.

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.

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.

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.
