  • Application Area: For recording of VOC profiles from plant and animal samples

"The system makes collection and analysis of VOC really easy. The ability to re-collect samples, adjust desorption conditions, split rates and internal standard addition allows customisation of system to a wide range of analytes and to sample with high dynamic range. "

  • Application Area:We are primarily using the Markes TD-100 for thermal desorption of TENAX tubes

"MAS purchased two of these units in the past year to replace earlier model thermal desorption units from another manufacturer. The replacements and a change to Markes was prompted by a desire to minimize instrument down time, move to a trap design, eliminate de-capping issues and increase our overall analytical sensitivity. Our use and reliance on these new instruments over the past 6 to 12 months has proven to be a sound investment. Specifically, the units are easier to operate and diagnose issues as the pressure is handled by the GC. Overall we have experienced more accuracy, significantly better precision and far less maintenance issues. We have found that the unit has particularly been beneficial in sensitive odor projects."
