Markes UNITY-Air Server-xr Air Monitoring System

Markes UNITY-Air Server-xr is a cryogen-free automated thermal desorption system for unattended on-line air monitoring.

UNITY–Air Server-xr™ is an air monitoring system that introduces a controlled flow of sample directly into an integral focusing trap, allowing automated on-line analysis of VVOCs and VOCs in air or gas. It’s ideal for round-the-clock air monitoring of volatiles such as PAMS ozone precursors and odorous species, especially in remote locations where unattended sampling at time specific intervals is necessary.

Norm Compliance: On-line automation is fully compliant with US EPA PAMS. The UNITY AirServer can also be quickly upgraded to allow tube automation to be fully compliant with US EPA methods TO-17 and 325, as well as ISO 16000-6, EN14662-1, ASTM D6196 and other key standards.

Features

Cryogen-free operation, fast cycle times and automated sequencing between at least three channels (sample, standard, blank) minimize user intervention and deliver optimum data coverage.
Best-Available Sensitivity
Quantitative retention of C2 hydrocarbons from up to 1L of air to enhance ozone precursor monitoring.
Uniquely fast trap desorption delivers sharp peaks and optimum detection limits for critical trace air pollutants.
Versatility and robustness
Mass flow-controlled sampling provides precise sample volumes and highly reliable data.
Split-less and high-split options extend the sample concentration range.
Completely inert flow path offers compatibility with the most challenging analytes.
Method-compliant tube desorption offered as standard. Upgradable to 100-tube automation.
