The Vocus Cork Analyzer (VCA) is a high throughput auto-sampler coupled to a high resolution TOF mass spectrometer. These combined technologies non-destructively test individual natural cork stoppers for the presence of TCA and other off-flavors and automatically sorts the stoppers according to the detected concentrations. The VCA is able to screen a single natural cork stopper in only 2 seconds, quantifying the TCA with a limit of detection of just 0.05 ng/L for TCA, with accuracy and precision superior to standard, destructive and time-consuming ISO-OIV methods.  Due to its high throughput, a single VCA system is able to analyze 1,800 corks/hour and about 10 million cork stoppers per year.
