The illustrated embodiments include a method of operating a SAW sensor to detect a sample in a fluid which includes the steps of: providing a SAW sensor with a functionalized detection lane in a handheld, portable assay device and sensor system; maintaining the functionalized detection lane of the SAW sensor dry until the sample is fluidically disposed in the detection lane; fluidically disposing the sample in the functionalized detection lane; removing fluid the functionalized detection lane to concentrate the sample in the functionalized detection lane to increase the probability of a specific antibody-antigen interaction; washing the functionalized detection lane so that substantially only the specific antigen-antibody interaction remains in the functionalized detection lane; removing fluid from the functionalized detection lane again; and measuring concentration of the sample while the functionalized detection lane is fluid-free.

ODOR DETECTION DEVICE, ODOR DETECTION METHOD, AND PROGRAM
An odor detection device (1) includes an odor sensor (10), environmental information measurement means (11, 12), odor information collection means (20), difference information acquisition means (21), and correction means (22). The odor sensor (10) detects information on an odor emitted from an odor source (2). The environmental information measurement means (11, 12) measures information on an environment, correlated with the amount of water vapor contained in surrounding gas. The difference information acquisition means (21) acquires the difference amount of water vapor, indicating a difference between information on an environment surrounding the odor sensor (10) and information on an environment surrounding the odor source (2). The correction means (22) corrects information on an odor, collected by the odor information collection means (20), on the basis of difference information acquired by the difference information acquisition means (21).
