Overview
Off-Flavor Analysis of Every Cork Wine Stopper
The Vocus Cork Analyzer tests individual stoppers for the presence of TCA and other off flavors and automatically sorts the stoppers according to detected concentrations.- High-Throughput Industrial Solution. The industrial scale autosampler and sorter enable automated processing of >30,000 stoppers per day.
- Trace-Level Detection in Seconds. TCA is quantified below the sensory threshold in a single stopper in 2 seconds.
- Adjustable Thresholds for Stopper Sorting. Analyzed stoppers are sorted into high precision TCA concentration categories.
- Fully Validated Scientific Method. Superior sensitivity, precision and accuracy compared to standard TCA measurement methods are demonstrated in a peer-reviewed scientific publication.
Method
Guarantee Cork Stopper Quality With Advanced Mass Spectrometry
The Vocus Cork Analyzer couples our fast, sensitive Vocus mass spectrometer to an industrial scale autosampler and sorter. Stoppers are analyzed directly without any soaking or destruction. TCA is measured quantitatively with high sensitivity and precision.
Linear Quantitative Response
The intensity of the signal recorded by the Vocus Cork Analyzer is directly proportional to TCA concentration, enabling accurate determination of TCA levels in individual cork stoppers.
Ultra-Low Detection Limits in Seconds
The Vocus Cork Analyzer rapidly measures TCA below the sensory threshold in individual cork stoppers and physically sorts each stopper according to the detected concentration.
Reproducible
The Vocus Cork Analyzer precisely reports TCA concentrations – reproducing the same results for individual stoppers measured repeatedly across weeks.

The Vocus Cork Analyzer is an Industrial Solution
Operation of the Vocus Cork Analyzer is fully automated for high-throughput analysis of cork wine stoppers in your production facility. Corks are processed in 3 simple steps.
- Load. Stoppers are loaded by a cork feeder.
- Analyze. An individual cork is analyzed for off-flavors in 2 seconds.
- Sort. Stoppers are sorted into user-defined categories based on the results of analysis.
