Fuente: Food Processing The TOFWERK Vocus Mass Spectrometer is a high-performance, robust real-time chemical ionisation time-of-flight mass spectrometer designed for trace-level detection of volatile organic and inorganic compounds (VOCs and VICs). Suitable for food and flavour scientists, it can provide sub-pptv detection limits, high mass resolution and rapid data acquisition, to enable comprehensive profiling of aroma, flavour and off-flavour compounds without sample preparation.

The Vocus CI Series provides good flexibility with interchangeable proton transfer reaction (PTR) and Aim Reactors that allow users to optimise ion chemistry for specific analytes or research needs. Its compact, modular design includes integrated tools and automatic connections for seamless operation in lab, industrial and mobile environments.

Applications range from food authentication and fermentation monitoring to spoilage detection and quality control. For example, in industrial settings, the Vocus Cork Analyzer couples the Vocus instrument with an autosampler for high throughput screening, processing over 30,000 wine stoppers per day and quantifying trichloroanisole (TCA) and other taint compounds in seconds.

With good sensitivity, selectivity and throughput, the mass spectrometer can provide manufacturers and researchers with a powerful tool to help ensure consistent flavour, freshness and product integrity.
