This document introduces UNITY(e) Thermal Desorber, which can analyze single standard sample tubes and extend the compatible sample range to include whole-air and gaseous phase samples by using Air Server/MCS06/08 accessories, such as continuous monitoring of air/gas streams or samples collected in whole-air containers such as canisters or Tedlar bags.
The Markes International Air Server/MCS06/08 is an accessory designed to extend the sample range of the UNITY(e) Thermal Desorber. It enables the analysis of whole-air and gaseous phase samples, such as those from canisters or Tedlar bags, in addition to standard single tubes. The system features automated sampling via software-controlled mass flow controllers and inert switching valves.

It analyzes whole-air and gaseous phase samples, such as continuous air/gas streams or samples collected in canisters or Tedlar bags.
Yes, if the sample is at low (<10 psi), atmospheric or sub-atmospheric pressure, a pump (p/n U-ASPM1 or U-ASPM2) is required to pull the gas-phase sample.
The system offers selection between three, six, or eight inlet ports depending on the specific accessory chosen.
All split and purge flows are settable between 5 and 100 mL/min, with higher ranges available on request.
