INTERACTION BETWEEN WHEY PROTEIN NANOPARTICLES AND FATTY ACIDS
Hassan, Z.M.R*, Awad R. A.*, El-Sayed, M. M. **, Mevat I. Foda**, Otzen, D.*** and Heba H. Salama**

Nanocomplexes can be formed from WPI with good cytotoxic effect to tumer cells using cis-vaccenic and linolenic fatty acids comparable to oleic acid. It was a new interesting observation being that the nanocomplexes formed of WPI with fatty acids has a comparable cytotoxcisty to that of a-LA and ß-lg and can be used in tumor therapy.

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.

Analysis of Dithiocarbamate Pesticides by GC-MS
Soma Dasgupta1,2, Sumaiyya Mujawar1, Kaushik Banerjee1, Hans-Joachim Huebschmann3, Paul Silcock4

Analysis of dithiocarbamate pesticides (DTCs) using an optimized GC-MS method is described. DTCs are not stable and cannot be extracted or analyzed directly. The purpose of this work was develop a reliable method for identification and quantification of residues.

Analysis of Multiresidue Pesticides Present in Ayurvedic Churna by GC-MS/MS
Manoj Surwade, Sunil T Kumar, Aarti Karkhanis, Manish Kumar, Soma Dasgupta, Hans-Joachim Huebschmann, Paul Silcock, Thermo Fisher Scientific

Analysis of Herbal powders or ‘churnas’ using an optimized GC-MS/MS method is described. As they have high amount of matrix co-extractives, they pose critical analytical problems. The purpose of this work was overcome the effect of the matrix and develop a reliable method.

Automated Solid-Phase Extraction of Oraganochlorine Pesticides from Drinking Water
Frans Schoustsen and Pranathi R Perati

A new method was developed to automate the capture and elution of Organochlorine pesticides from drinking water. The concentrated analytes were then analyzed by GC with Electron Capture Detection (ECD).

GC-MS/MS Analysis of Pesticide Residue in Green Tea Extracted by QuEChERS with Acetonitrile as Final Solvent
Cojocariu C., Morgan P., Silcock P., Godula M

QuEChERS involves an initial step when a few grams of the sample are extracted with acetonitrile followed by a clean-up step (with dispersive-SPE) used to remove, to a certain extent, unwanted matrix compound (such as pigments, sugars, organic acids). With QuEChERS, the final extract ends up with the pesticides in acetonitrile, which, being polar solvent, can be
problematic in GC-MS.
