Breathe Free - the open source breath sampler consortium

The challenge

No standard method exists for the capture of exhaled breath samples and the methods currently used vary in the analytical approach.

Breathe Free’s aims

  • Assemble a community of researchers interested in breath based diagnostics.
  • Share our collective knowledge of breath sampling.
  • Jointly design a breath sampler that can be used with a range of analytical instruments.

Open source & free to access

Our designs are open source and will be made freely available to anyone. By sharing the expertise of many we hope to solve the thorny issues of standardisation of breath sampling and by giving this design away we hope to progress the field of breath based diagnostics.
