<p>An apparatus for ex vivo measurement of blood sugar levels comprises a light aggregate (1) providing a single or pairs of narrow light bands in the wavelength range of 1-40 mu m, at least one band lying in the range of 3-10. Light is transmitted to an attenuated total internal reflection device (2). The sample with the substance to be measured is placed on a surface (3) of said device (2) to be transversed by the light which is more or less absorbed by the substance. A detector (5) converts the intensity of light emanating from the attenutated total reflection device (2) into an electric signal which is handled by a computer (7) calculating the concentration of the substance by unvariate analysis directly comparing pairs of wavelengths for each substance.</p> |
