The transition of winemaking from an art to a more exacting science is dependent upon the detection and understanding of nutrient and flavor loss and accumulation during the processing. In addition, the ability to detect and quantify potential contaminant compounds such as biogenic amines, pesticides, herbicides, fungicides, and phytotoxins is also of critical importance. The work detailed in this poster details how ultra-high resolution TOFMS with multiple reflections was utilized to generate fingerprints of several wines and their pre-harvest wine grape juices.
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.
