Optical analysis method for liquid in a sample container and analysis device for carrying out the method

摘要

The invention relates to a method for optically analyzing a sample liquid (34) contained in a sample container (24a-h), wherein the sample liquid (34) contains at least one substance (40) in at least partially dissolved form, comprising the following steps: providing at least one sample container (24a-h) filled with sample liquid (34); illuminating the at least one sample container (24a-h) by means of a light source (18a-h); and recording an image of an identification pattern (32a-h) associated with the at least one sample container (24a-h) by means of an image recording device (22) that produces image data, wherein the optical path (OP) is selected in such a way that the sample liquid (34) contained in the at least one sample container (24a-h) lies at least partially between the image recording plane (36) of the image recording device (22) and the identification pattern (32a-h). The invention further relates to an analysis device for carrying out the method.

1. A method for the optical analysis of a sample liquid (34) contained in a sample container (24a-h), wherein the sample liquid (34) contains at least one substance (40) in an at least partly dissolved form, comprising the steps of:
providing at least one sample container (24a-h) filled with a sample liquid (34); illuminating the at least one sample container (24a-h) by means of a light source (18a-h); and capturing an image of an identification pattern (32a-h) associated with the at least one sample container (24a-h) by means of an image recording device (22) which generates image data, wherein the optical path (OP) is selected in such a way that the sample liquid (34) contained in the at least one sample container (24a-h) is at least partly situated between the image recording plane (36) of the image recording device (22) and the identification pattern (32a-h), wherein, after the image of the identification pattern (32a-h) has been recorded, the generated image data are evaluated and it is established whether the identification pattern (32a-h) can be identified (S05, S06) through the sample liquid (34), wherein, if the identification pattern (32a-h) of the at least one sample container (24a-h) is identified, it is established how large the error correction is and derived therefrom whether the substance (40) is partly or completely dissolved in the sample liquid (34).
