1. A breath-condensate analysis cartridge suitable for incorporation into an exhalation device, the cartridge comprising;
a condensation zone to receive exhaled breath, the condensation zone having a peripheral region;
an analysis chamber in which a sample is analyzed;
a surface of the condensation zone acting to create a fluid flow path in the peripheral region;
the condensation zone being linked to the analysis chamber by a fluid flow path through the peripheral region;
a lip to at least partially cover the peripheral region, the lip co-operating with the condensation zone to form a capillary to control fluid flow,
wherein the condensation zone is coated or formed of a hydrophilic material.
