Abstract: A breath sampler for collecting a breath sample from a patient is disclosed. The breath sampler has a non-rebreather part including a sample inlet, a one-way outlet valve downstream of the sample inlet, and an air inlet. The one-way outlet valve and the sample inlet define a first portion of an internal breath flow pathway therebetween. The air inlet is arranged to be closed by a one-way inlet valve arranged to allow air to enter the non-rebreather part. The breath sampler also has a sample delivery part in fluid communication with the non-rebreather part at an upstream end via the one-way outlet valve. The sample delivery part defines a second portion of the internal breath flow pathway, and has an air diverter, a sample outlet, a return inlet and a sample collection chamber connector. The air diverter is arranged to divide the sample delivery part into an upstream portion upstream of the air diverter and a downstream portion downstream of the air diverter and is configured to divert the breath sample into a sample collection chamber including a liquid capture interface. The sample collection chamber is coupled to the sample collection chamber connector and includes a liquid capture interface.
