Highly Accurate Measurements of Ochratoxin A (OTA) in Different Foodstuffs
Poster Jan 17, 2011
Andreas Breidbach, J. Stroka and F. Ulberth
In 2010 the proficiency tests consisted of a cereal mix, paprika powder, and green coffee naturally contaminated with OTA, a toxin produced by the moulds Aspergillus ochraceus and Penicillium verrucosum. The work in the poster details how Exact-Matching Double Isotope Dilution Mass Spectrometry (EMD-IDMS) was utilised by the Institute to assign values for the three materials.
Application of Solid Phase Micro Extraction (SPME) and On‐Fiber Derivatization to Detect Precursors of Biomolecules in the study of Proto‐metabolismPoster
In the studies of origins of life, plausible synthetic reaction pathways to form biological relevant molecules, or building blocks of proto‐bilayer lipids, protein, RNA, and DNA in the primitive environment have been investigated intensively.READ MORE
A New Tool for the Automated Sample Preparation of Whole Blood Samples by LC-MS using a Commercial AutosamplerPoster
Automated sample preparation reduces the costs per sample and minimizes sample handling errors. Usually expensive and highly specialized pipetting robots are used. However, most of these systems are not designed with a direct interface for LC-MS applications. In addition common pipetting systems are not optimized for smaller scale sample series. Here we present a new tool for liquid handling of whole blood samples and direct sample injection.
