APPLICATION OF LIQUID CHROMATOGRAPHY WITH UV DETECTION FOR DETERMINATION OF PLANT GROWTH REGULATOR IN COMMON PLANT FERTILIZERS
Borowczyk K., Wyszczelska-Rokiel M., Stachniuk J., Chwatko G., Glowacki R.

1. The methodology allows facile and accurate determination of IBA in common plant fertilizer samples.
2. The analytical figures of linearity, precision and recovery shown during the method validation procedure are well within the criteria for biological sample analysis.
3. In temperature -18, 4 and 25 °C the analyte stays stable for 6 h.
4. The assay should help in control of phytohormones concentration in plants and fertilizers.

MS Data Processing With Full Flexibility Of Universal Processing Software
Frans Schoutsen, Barbara van Cann, Vincent Jespers, Michal Godula

Liquid Chromatography (LC) in combination with triple quadrupole Mass Spectrometry (MS) is more and more a common analysis technique in routine laboratories. Especially when using MS/MS selected reaction monitoring (SRM) for a large number of components data handling can be a bottle neck. This poster will show MS data processing of pesticides in water samples using an already established chromatography data system which is now also capable of processing large quantities of MS data.

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.

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.

New Sorbent from Agro-industrial Waste and its Potential Use in 17ß-Estradiol and 17α-Ethynylestradiol Removal
Suzimara Rovani*, Éder C. Lima, Renato Cataluña, Andreia N. Fernandes

In recent years, the increasing introduction of new chemicals in the market, and the development of more accurate analytical methods, added a variety of endocrine disruptors compounds (EDC). Even though they are found in very low concentrations (range of ng L-1) there is still a lack of knowledge about long-term risks of EDC for non-target organisms as well as for human health.

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.
