◼ Analysis : VOCs(Volatile organic compounds) and VICs(Volatile inorganic compounds)

◼ Reagent Ions : PTR (H₃O⁺), NH₄⁺, O₂⁺, NO⁺, I^–, Br^–

◼ Models 

Reduces wall losses and focuses product ions and Maximize analyte signals with combination of Vocus reaction cell, ion cooling interface, and sensitive TOF mass analyzer

Sub-ppt limits of detections in seconds and up to 10x the sensitivity Of other commercial PTR-MS

Mass resolving power up to 15000 enables identification of isobaric compounds in complex mixtures Identification of analytes and confirmation of peak assignments based on exact mass and isotope patterns

Vocus CI-TOFs are available with two interchangeable CI reactors – Vocus PTR and Vocus Aim –  each optimized  to target different classes of compounds.  Configure a system to address your varied and evolving requirements.

Headspace autosampler, Liquid calibration system  

Vocus measurements are selective for specific classes of volatile organic and inorganic compounds (VOCs and VICs), and analytes are ionized with limited fragmentation so that molecular ions are observed. These features – along with high mass resolving power  – allow real-time characterization of complex mixtures without chromatography.
