A SAMPLE COLLECTOR

The disclosure relates to a sample collector for collecting airborne particles exhaled by a human being, comprising: a sampling compartment for receiving a flow of air; a particle capturing substrate for capturing the airborne particles in the flow; an analysis compartment; and a substrate clamping device comprising an optical window and a support member; wherein the sample collector is reconfigurable between a sampling configuration in the sampling compartment for passage of the flow through the particle capturing substrate and an analysis configuration, wherein in the particle capturing substrate is arranged in the analysis compartment, the optical window is aligned with an aperture for allowing optical access to the particle capturing substrate is allowed; andwherein, during reconfiguration from the sampling configuration to the analysis configuration, the substrate clamping device and the particle capturing substrate are moved together to the analysis compartment while the substrate clamping device is brought to the closed state.
