The MTS-32™ Pro from Markes International is a compact, portable automatic sampler designed for unmanned, sequential air sampling onto a series of thermal desorption sorbent tubes.
As the technological evolution of the classic MTS-32 model, the Pro version introduces advanced programmability and automation features.
It is the ideal instrument for monitoring and analytically understanding the temporal profile, persistence, and dissipation of volatile organic compounds (VOCs) and aromas in the environment or from consumer products.
Key Features
- Advanced programmable automation: Enables unattended sequential air sampling for up to 32 standard 3.5-inch tubes, minimizing manual operator intervention.
- Precise temporal profiling: Ideal for real-time mapping of sequential fragrance release and the evolution of volatile compounds over time.
- Constant sampling volume: The integrated constant-flow pump technology ensures maximum accuracy by collecting the same volume of air on each tube, regardless of tube impedance variations.
- Total sample integrity: Sorbent tubes remain protected and sealed thanks to proven diffusion-locking technology, eliminating the risk of external contamination or analyte loss.
- Portable and robust design: Housed in a weather-resistant (showerproof) case constructed from low-outgassing materials to prevent sample artifacts.
Applications
The MTS-32 Pro system enhances sample preparation and air monitoring capabilities across various application sectors:
- Fragrance research and development: Studying the longevity, intensity, and release behavior of perfumes (e.g., air fresheners, cosmetics) under real-world conditions.
- Food & Beverage: Monitoring the time-dependent profiles of aromas and odorous compounds released from food products.
- Environmental monitoring and Indoor Air Quality (IAQ): Time-resolved, sequential sampling of indoor and outdoor air to track fluctuations in organic vapor concentrations over hours or days.
- Material emissions testing: Paired with systems like the Micro-Chamber/Thermal Extractor, it allows the sequential capture of chemical emission kinetics from solids and liquids.
Seamless TD-GC/MS
IntegrationSequential samples collected with the MTS-32 Pro are ready for direct analysis via thermal desorption coupled with gas chromatography-mass spectrometry (TD–GC/MS). The system interfaces seamlessly with Markes' high-throughput automated thermal desorbers, such as the TD100-xr or the single-tube UNITY-xr, optimizing the laboratory's entire analytical workflow.ottimizzando l'intero workflow analitico del laboratorio.
