Disease diagnosis via breath and bio-monitoring: Optimizing the analytical performance of sorbent tube sampling and thermal desorption–GC–MS
9 September 2021

Breath monitoring has the potential to provide diagnostic solutions for a wide range of diseases. However, its application remains challenging, and many aspects must be taken into consideration when developing and optimizing sampling and analytical parameters.

In this application note, Markes International describes how to optimize the analytical performance of thermal desorption (TD) for those carrying out routine or research monitoring of breath for disease diagnosis. Download the full note below to explore guidance on the major steps in the sampling and laboratory workflow, discover the main analytical challenges, and gain advice on which features and parameter ranges to select.
