Breath sampling

Breath sampling is a valuable approach for obtaining information used for disease diagnosis, monitoring of metabolic stress and personal exposure to chemicals. Breath samples can be collected using a number of techniques, which can then be used with thermal desorption to extract and concentrate the VOCs, maximising sensitivity for analysis of trace-level target compounds while minimising interferences.

With the growing interest in breath monitoring, alternatives have emerged to the long-established use of Tedlar® bags for sampling breath.

Markes’ BioVOC-2™ is an easy-to-use device for sampling of VOCs in breath that transfers the volatiles directly onto sorbent tubes for analysis by thermal desorption.
