Abstract

A method for determining an analyte of a liquid sample in a cuvette includes providing a cuvette, a reagent, a barcode, an icon on the cuvette and a liquid analysis device comprising a photometer, a rotation device, a camera, a calibration data memory storing first calibration data, and an input device which manually inputs second calibration data. The cuvette is inserted into the liquid analysis device and is rotated to align the icon with the camera. The icon is read with the camera and the icon read compared with an icon model stored in the liquid analysis device to determine whether it corresponds thereto. The liquid sample is subjected to photometry based on the first calibration data if the icon read corresponds to the icon model. If not, the input apparatus is activated and the liquid sample is subjected to photometry on the basis of the second calibration data.
