Description:

Dr. Markus Huettel and Alireza Merikhi have developed a device and method for rapid assessment of sensor response times as the sensor is switched rapidly between two or more testing fluids discharged from a multi-fluid jet nozzle. An embodiment of the novel device is a dual-fluid jet nozzle that ejects two distinct jets of testing fluid at the same velocity through a single nozzle discharge aperture divided by a sharp edged boundary wall, which effectively create a single jet stream containing two fluids separated by a sharp boundary. An embodiment of the novel device may be configured to discharge more than two jets of fluid to create a jet stream containing multiple fluids separated by sharp boundaries. A sensor tip is first exposed to a first testing fluid and then rapidly exposed to a second testing fluid. The sensor’s output may then be assessed to determine its response time.
