Vocus CI-TOF: The Ultimate Solution for Real-Time Trace Gas Analysis
Detect the invisible in real time.
Elevate your analytical capabilities with the world’s most advanced Chemical Ionization Time-of-Flight technology.
The Vocus CI-TOF delivers unparalleled speed and sub-ppt (parts-per-trillion) precision, making ultra-trace VOC detection faster, highly reliable, and accessible for any advanced monitoring project.
Vocus CI-TOF: Cutting-Edge Technology for Advanced Analytics
Real-Time Identification of Trace Gases at Ultra-Low Concentrations
The applications for this groundbreaking technology are vast, ranging from breath analysis for disease biomarker detection to indoor air quality (IAQ) monitoring and material emissions evaluation.
As the health impacts of Volatile Organic Compounds (VOCs) and inorganic compounds—even at trace levels—become increasingly documented, the need for immediate accuracy is critical. By delivering real-time analysis, the Vocus CI-TOF captures complete kinetic profiles, providing the comprehensive and dynamic data essential for exhaustive, high-level studies.
Real-Time Kinetic Analysis and Emission Profiling
The core strength of the Vocus CI-TOF lies in its real-time gas analysis capabilities, delivering highly precise kinetic emission profiles. The advanced software empowers you to either track specific target compounds or continuously identify untargeted analytes as they emerge.
To guarantee optimal sensitivity and selectivity across all chemical classes, the instrument can be configured with various interchangeable ion sources and reactors, perfectly tailored to your specific application.
The VOCUS CI-TOF, manufactured by TOFWERK, is a flight-time spectrometer with unique specifications that make it a cutting-edge tool:
- High resolution up to 25,000 M/ΔM
- Several ions available, interchangeable in seconds to promote selective detections.
- 2 types of reactors available and interchangeable: PTR or AIM with each several ions available.
Operating Principle:
The VOCUS CI-TOF is based on the principle of Time Of Flight mass spectrometry: The gaseous sample to be analysed is introduced into the analyser and then ionized into the reactor by the ion of your choice; The different compounds will be separated and transferred to the detector more or less quickly depending on their m/z ratio. The flight time mass spectrometry is recognized for its resolution and sensitivity.
Chemical ionization also has the advantage, depending on the ion, of creating little or no fragmentation, facilitating identification. The choice of the ion and the reactor makes it possible to concentrate on certain chemical classes of compounds (inorganics, bases, acids, etc.) and to detect them in an ultra sensitive way:
The PTR reactor is a powerful system for analyzing a wide range of volatile organic compounds (VOCs). This allows to target various ranges of compounds with high quality results.
The Aim reactor promotes the rapid and sensitive detection of traces of organic and inorganic compounds. The flexible chemistry of reactive ions allows selective ionization with independent moisture performance, providing extremely sensitive detection in various applications with less fragmentation.
Analysis time: 1 s at 1 min (depends on reactor and model)
Configuration: 1 interchangeable reactor (PTR or AIM). Up to 6 ions
Detection range: < 5 ppt to ppmv
Options:
– expired air sampler
– battery
– field mobility option
The Vocus CI-TOF series is available in several more or less sensitive and resolutive versions according to your needs. Consult us to select the version suitable for your application.
Details of the versions in the brochure in the Documentation tab.
NB Interchangeable reactors only on the Vocus CI series.
The Vocus PTR-TOF is only available with a PTR reactor.
The Vocus B is only available with an AIM reactor.
Why Choose the Micro GC Fusion®?
The flexibility of the CI-TOF VOCUS allows us to address a wide range of applications and explore complex compositions in detail. It is thus possible to change reactor and ions for better selectivity.
For smaller needs PTR or Aim versions only are available with lower resolutions.
