Abstract:
1. A method for the assessment of at least one quantity parameter and/or at least one quality parameter of biological particles in a liquid analyte material, comprising applying a volume of a liquid sample representing the analyte material or particles isolated from a volume of liquid sample representing the analyte material, to an exposing domain from which exposing domain electromagnetic signals from the sample in the domain can pass to the exterior, transmitting, onto the sample, light from a light emitting diode, exposing, onto an array of active detection elements, an at least one-dimensional spatial representation of fluorescent signals having passed from the domain, the representation being one which is detectable as an intensity by individual active detection elements, under conditions which will permit processing of the intensities detected by the array of detection elements during the exposure in such a manner that representations of electromagnetic signals from the particles are identified as distinct from representations of electromagnetic signals from background signals, processing the intensities detected by the detection elements in such a manner that signals from the particles are identified as distinct from background signals, and correlating the results of the processing to the at least one quantity parameter and/or the at least one quality parameter of the liquid analyte material.
