Analysis of optical data using histograms

The system has a detection unit for detection of light intensities, which are radiated by partial areas of detection areas of a test unit, and an evaluation unit determining frequency distribution for the detected intensities, where the distribution has a maximum generated by an uncoated partial are...

Beschreibung
Zusammenfassung:	The system has a detection unit for detection of light intensities, which are radiated by partial areas of detection areas of a test unit, and an evaluation unit determining frequency distribution for the detected intensities, where the distribution has a maximum generated by an uncoated partial area or a reference area and another maximum generated by a coated partial area. The evaluation unit selects one of the intensities based on the distribution and determines the concentration of an analyte from the selected intensity. Independent claims are also included for the following: (1) a method of determining concentration of analyte in fluid (2) a method of quality control of detection area of a test unit (3) an instrument for determining concentration of analyte in the fluid.
