Qualitative Comparison of Wine Process Samples with UHPLC and Ultra-High Resolution TOFMS

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.
