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, Rapid And Reliable Determination Of Dissolved Gases In Water By Static Headspace – Gas Chromatography
A. Caruso, M. Santoro, F. Bedini, P. Magni, S. Pelagatti

Purpose: Exploring the possibility to perform a quantitative determination of dissolved gases in water in a reliable and accurate way. Methods: The quantification of dissolved gases is performed by building a calibration curve spiking blank water samples with increasing quantities of saturated water followed by headspace sampling and GC/ FID analysis. Results: The results show good correlation factors and limit of quantification lower than 10ppb for the four gas analyzed.

Characterization of Antibody-Drug Conjugates by SEC with Combined Light Scattering
Chris C. Broomell

Drug Antibody Ratio (DAR) is a critical factor to the effective design of antibody-drug conjugates (ADC). This poster presents a method for DAR determination based on SEC-MALS in conjunction with UV absorption and differential refractive index detection.

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.

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.
