Proud Sponsor of CSA 2023

Our Vocus Cork Analyzer team is excited to sponsor this year’s International Conference on Cork Science and Applications (CSA) in Vila Nova de Gaia, Portugal from September 7 – 8. CSA aims to establish a forum for researchers, producers and companies to make contacts, get acquainted with new ideas, and establish partnerships to optimize existing solutions and generate new cork products.

Vocus Cork Analyzer

The Vocus Cork Analyzer accelerates cork wine stopper production and ensures that producers deliver the highest quality cork wine stoppers to the winemakers and consumers who rely on purest natural corks.

With the next generation Vocus Cork Analyzer, trace levels of TCA and other off-flavors are quantified in individual stoppers in only 2 seconds per cork. This increased speed provides a throughput increase of +50% compared to the previous model, allowing the individual screening of more than 10 million corks/year with a single instrument. In addition to the accelerated screening, both mass spectrometry analysis and mechanical automation have been optimized, all while keeping unparalleled sensitivity, precision and accuracy.

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.

Measured TCA concentrations for a set of 300 stoppers (2 second/cork; 10 minutes total; logarithmic plot). A sensory panel identified stoppers shown in red as being contaminated with TCA and determined those in blue to be clean. The Vocus measurements identify the same contaminated corks as the sensory panel, and further identify many other stoppers with concentrations close to 0.5 ng/L.
