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.
The Vocus Cork Analyzer precisely reports TCA concentrations – reproducing the same results for individual stoppers measured repeatedly across weeks.
