The Importance of Reliable and Efficient Sample Preparation in the Development of a Novel Forensic Method to Detect Diclofenac Residuesin Vultures and Livestock Animals
10 Sept 2015A technique was developed to identify diclofenac residues in vultures and livestock animals by GC-MS. This paper reviews the development of this methodology, the technical challenges faced, with emphasis on sample preparation, and the role of the miVac sample condenser in increasing the overall efficiency and reliability of the method and its validation.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.
