Vocus chemical ionization mass spectrometers deliver sub-ppt limits of detection for the measurement of VOCs and VICs, optimized for use in laboratories, industrial sites, and mobile applications.

Vocus CI-TOF reports concentrations of volatile organic and inorganic compounds (VOCs and VICs) with part-per trillion (ppt) limits of detection. Vocus CI-TOF limits fragmentation so that molecular ions can be observed in real-time at high-resolution, allowing for the characterization of complex mixtures without traditional chromatography methods.
