The Bio-VOC breath sampler is a simple device designed for non-invasive biological exposure monitoring i.e. measurement of the total body burden of volatile organic compounds (VOCs). Elevated levels of one or more VOCs within the body may indicate environmental or occupational exposure (i.e. absorption of chemicals from the environment or workplace via skin absorption, ingestion or inhalation) or that the individual concerned has a clinical condition (some diseases can be diagnosed from a characteristic pattern of VOCs in the breath).
Constructed of safe, non-emitting plastic the Bio-VOC sampler may be operated with minimal training and without medically qualified staff in attendance. Each Bio-VOC is supplied with an individual disposable
cardboard mouthpiece.
Once the breath has been collected, a screw-in plunger is used to steadily discharge the sample into a sorbent tube (or a direct read-out instrument). After collection onto a sorbent tube the sample is sealed and the breath sample is stable for transportation and analysis; a distinct advantage over blood and urine samples.
The Bio-VOC sampler may be re-used by the same individual, using a new mouthpiece, typically over the course of a day, but is then discarded or cleaned before re-use.
