Measurement of Beta-amyloid in blood by scattered light, for the diagnosis of Alzheimer's disease, a calibration solution is prepared of a carrier fluid and two monomers with structured particle dimensions
Analysis of samples using scattered light measurement, a calibration solution is prepared as an initial solution. It has a carrier fluid with two monomers where their particles do not exceed certain dimensions. The second monomer can react with the first monomer to a dimer and/or oligomer and/or polymer particles which breach the given size. T : Analysis of samples using scattered light measurement, a calibration solution is prepared as an initial solution. It has a carrier fluid with two monomers where their particles do not exceed certain dimensions. The second monomer can react with the first monomer to a dimer and/or oligomer and/or polymer particles which breach the given size. The initial concentrations of the two monomers are set so that reactions can be measured by scattered light. The apparatus has a cylindrical measurement chamber (2) with parallel flat windows (5,6) at the ends. Radial inputs (7,8) and outputs (9,10) are between the windows. The measurement chamber is of a fluorinated plastics, and/or the windows are of plastics or borosilicate and/or sapphire glass.
