Abstract: The invention relates to a novel method and a device for quantitative concentration measurements of protein bound and middle sized uremic toxins and advanced glycation end-products in the biological fluids, preferably in the spent dialysate. Invetion combines unique spectral ranges of fluorescence and absorption to determine concentration of uremic toxins, such as indoxyl sulfate, beta-2-microglobulin and 4-pyridoxic acid in a way that provides significantly higher precicion than previously known solutions.

Abstract: The present invention relates to an optical system having a chamber (26) for receiving an element (E) of body fluid or tissue or environmental sample to be characterized by the optical system, a light source (5) for illuminating the chamber (26) with light, and a spectrometer (6) for recording a spectrum of light originating from the chamber (26), wherein the light source (5) comprising two separate LEDs (5A, 5B) to emit light having at least two spectral maxima of different wavelength ranges, and the light source (5) is coupled to the chamber (26) such that the light is directed from the light source (5) to the chamber (26) when the light source (5) is activated. Further, the present invention relates to a method for determining a parameter with an optical system, wherein the optical system comprises a chamber (26) for receiving an element of body fluid or tissue or environmental sample to be characterized by the optical system, a light source (5) for illuminating the chamber with light, and a spectrometer (6) for measuring a spectrum of light originating from the chamber (26), wherein, in order to determine a parameter representing a property of the element, light having at least two spectral maxima of different wavelength ranges are generated by separate LEDs (5A, 5B) and is directed onto the element, a spectrum comprising reflected components of the light, scattered components of the light, and/or light caused by raman scattering or fluorescence of the element is measured with the spectrometer (6), and the parameter is determined by evaluating the spectrum.

Abstract: The invention relates to a method for electromagnetic spectroscopy of a sample, the method comprising: - Delivering an excitation beam of electromagnetic radiation to a first portion of a sample to obtain emission, or elastic or inelastic scattering of photons, said photons having a wavelength in the visible range, from molecules forming the sample; - Illuminating the first portion of the sample with a visible light, said visible light being switched on and off at a first frequency, so that illuminated time intervals and non-illuminated time intervals of the sample are defined; - Detecting said emitted, or elastically or inelastically scattered photons having a wavelength in the visible range during said non-illuminated time intervals; and - Obtaining spectroscopy information from said detected emitted, or elastically or inelastically scattered photons. It also relates to a system for electromagnetic spectroscopy of a sample.
