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.

Benefits of breath sampling

  • Representative of VOCs in the bloodstream.
  • Non-invasive, unlike traditional blood and urine monitoring.
  • Eliminates time-consuming sample preparation prior to GC analysis.
  • Avoids the need for clinically trained personnel to collect samples.
  • Allows VOCs indicative of a variety of medical conditions to be rapidly profiled, including pulmonary disease, asthma, and asbestos-induced lung cancer.
