Unattended sequential sampling onto a series of sorbent tubes

The MTS-32 allows air to be pulled, sequentially, through a series of up to 32 industry standard sorbent tubes using constant flow pump technology.  The constant flow pump ensures that the same flow rate and volume of air is sampled onto each tube in the sequence regardless of impedance variations. 

Sampling times (1 minute - 99 hours) and flows (5-100 ml/min) may be user selected.


Diffusion-locking Technology

While outside the sampling period, sorbent tubes are sealed using Markes International patented* diffusion locking technology which prevents both diffusive ingress of atmospheric contaminants and loss of retained volatiles from sampled tubes.  The diffusion locking technology is either configured into DiffLok™ caps for use with standard sorbent tubes or incorporated inside Markes unique SafeLok™ tubes. 


Field Monitoring
The MTS-32 is a standalone, battery powered device housed in a compact, showerproof box.  It is ideal for field monitoring applications and will operate for over 40 hours on a fully charged battery.  Adaptors are available for mains power operation.  The battery or mains electricity adaptor maintains a supply of power to the recommended constant flow pump (FLEC^® pump) as well as powering the sequential sampler itself. 

The MTS-32 can be adapted to sample sequentially from a discrete gas or air line (please contact Markes International directly enquiries@markes.com )
