| 摘要 |
The invention relates to a method for at least partially applying a hydrophilic polymer to a measurement channel of a sensor cartridge that can be replaceably inserted in an analyzer, said measurement channel comprising at least one sensor element. The method is characterized in that a sensor cartridge is inserted in the analyzer, an aqueous solution containing chitosan or a chitosan derivative is introduced in the measurement channel of the sensor cartridge, and following a residence time the aqueous chitosan solution is replaced with a gaseous or liquid medium, wherein residues of the chitosan or chitosan derivatives remain on the inside surface of the measurement channel and hydrophilize said surface. |
