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.

Identifying Unknown Chemicals and Disinfection Byproducts in Swimming Pools and Hot Tubs
Jonathan D. Byer, Susan D. Richardson, Eric J. Daiber, Sridevi Anduri Chowdary, Joe Binkley, Jeff Patrick

DBPs were identified in finished water, tap water, swimming pool water, and hot tub water that were not present in the source water. High Resolution Deconvolution was used effectively to identify a greater number of peaks in the chromatogram than by nominal resolution MS.

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.

Method Optimization for Comprehensive Characterization of Petroleum with High Resolution Time-of-Flight Mass Spectrometry Platforms
Clecio F. Klitzke, David Alonso, Kevin Siek, Elizabeth Humston-Fulmer, Joe Binkley, Jeff Patrick

These results show the utility of high resolution time-of-flight mass spectrometry with high mass accuracy for comprehensive petroleomic studies. GC-HRT MS is especially useful for adding structural information in the analysis of complex samples like crude oil.

Crude Oil And Asphaltene Characterization by Pyrolysis Coupled to Gas Chromatography High Resolution Time-of-flight Mass Spectrometry
Clecio F. Klitzke, David Alonso, Joe Binkley, Jeffery Patrick

Py-GC-HRTOFMS analysis with high resolution and high mass accuracy is crucial for identification of crude oil and asphaltene pyrolysis products by unequivocal chemical formula assignment, with enhancement of sensitivity and selectivity. Analysis of petroleum and respective asphaltene fractions from diverse geographical origins are under evaluation as part of future work.

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.
