Request InfoOlythe SASA gas sensor measuring acetone level in exhaled air from Olythe SAS can aid in the diagnosis of certain pathologies such as ketosis or diabetic ketoacidosis. The OCIEngine sensor uses IR spectroscopy technology and consists of a measuring tank traversed by IR radiation. When the exhaled air passes through this cell, the molecules of interest absorb some of the radiation, which reduces the intensity of the optical signal. The concentration of the gas can therefore be calculated according to the Beer-Lambert law of physics. The fluctuation of the IR radiation emitted in contact with the...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2022 IssueOptical Spectrum AnalyzersThe AQ6375E and AQ6376E optical spectrum analyzers from Yokogawa Europe BV, Test & Measurement combine short- and mid-wavelength IR with extreme optical precision to aid in the development of...BioPhotonics Jan/Feb 2023 IssuesCMOS CameraThe ZL41 Cell sCMOS camera from Andor Technology is designed for life science researchers.
