CASPER Clean Air Supply
Use the ReCIVA Breath Sampler in any clinic with a clean & portable air supply
- Ensures breath samples are not contaminated by external VOCs
- Removes need for clean air supply line
- Portable system allows sampling to take place in the most convenient location
CASPER has been developed as part of the LuCID project as an accessory to supply a consistent flow of air, free of volatile organic compounds (VOCs), to ensure that all VOCs captured by ReCIVA have come from the patient's breath. A high purity air supply is vital to make sure that breath samples can be collected reliably and reproducibly. The complete system is entirely portable and can be wheeled to wherever the patient is in the clinic.
ReCIVA and CASPER have been designed with support from the Breathe Free Consortium of leading breath specialists around the world.

How does it work
How does CASPER work?
Modern gas analysis techniques such Owlstone’s FAIMS technology are starting to make non-invasive, point of care disease diagnosis from human breath analysis a reality. The identification of chemical disease biomarkers in human breath requires detection of extremely low concentration VOCs in patient breath. Such analysis is sensitive to the presence of ‘background’ VOCs in the ambient environment - i.e. the air that a patient breathes in before exhaling into a collection device such as the ReCIVA breath sampler. There are many ambient sources of unwanted VOCs even in clean, clinical environments, such as cleaning products, cosmetics, perfume, residual paint solvents etc. To minimise unwanted background VOCs in breath samples collected with the ReCIVA sampler, the CASPER clean air supply scrubs VOCs from the ambient air supplied to the patient.
CASPER is supplied with everything you need for a clean air supply. To maximise portability, all the components fit onto a compact stainless steel trolley. CASPER uses a mains operated air pump to take ambient air and pass it through an air filter/scrubber unit that removes unwanted VOCs from the air supplied to your patient. The patient will breathe in air cleaned by CASPER, ensuring that VOCs present in the collected sample are not ambient chemical contaminants from the surroundings. CASPER includes the following components.
