Multi-tube sequential sampler

The MTS-32™ is a compact, portable sampler for the unattended sequential sampling of air onto a series of sorbent tubes. Constant-flow pump technology ensures that the same volume of air is collected onto each tube.

Who uses the MTS-32?

The MTS-32 is ideal for analysts needing monitor the concentrations of organic vapours in air as they fluctuate over extended time periods. 

Product benefits

  • Labour-saving – leave the MTS-32 in the field and retrieve it at the end of the extended sampling period.

  • Obtain reliable results thanks to the constant-flow pump and diffusion-locking tube technology.

  • Peace-of-mind – you are buying a quality product from the recognised leader in thermal desorption instrumentation.


  • Sequentially samples on up to 32 × 3½-inch tubes.

  • Constant-flow pump ensures consistent sample volumes regardless of variations in tube impedance.

  • Diffusion-locking technology (Markes’ SafeLok™ tubes or DiffLok™ caps) prevent sample losses and ingress of contaminants.

  • Integral fan continually refreshes the air inside the case, ensuring that the air sampled accurately reflects the immediate environment.

  • Powered by mains electricity or a battery (will run for over 40 hours on battery).

  • Protective gauze across the fan inlet prevents particulates or wildlife from entering.

  • Constructed of low-outgassing components.

  • Field-portable – the MTS-32 can be used virtually anywhere.


Key Applications

  • Monitoring diurnal fluctuations of pollutants in ambient air.
  • Continuous monitoring of emission events in industrial locations.
