We have built a validated process for the simple analysis of wine components using only signature peaks and multiplets. An extended capability makes this possible, together with a semi-automated work flow that allows the trained user to quickly achieve an analysis that is checked and correct. [1, 2] After analysis, results are exported and automatically uploaded to a corporate database.
We shall demonstrate the program features that make this analysis possible, and show results for a wine analysis. A surprising level of analysis can be achieved, with >50 metabolites reliably quantified from a single 600 MHz 1H NMR spectrum. Quantification results were validated through certified compound additions. The process is part of a streamlined analysis that is performed on ca. 50 samples per day per analyst.
