Patent number: 9091639Abstract: The invention relates to a method for calibrating and/or adjusting an analytical device for chemical substances. A predetermined concentration of a chemical substance in a reference liquid is measured by mixing the reference liquid with a reagent for producing a color change, followed by irradiating with light of a predetermined wavelength. Based on the absorption of the light by the reference liquid, a concentration is determined, which is compared with the predetermined concentration of the reference liquid. In the case of which a calibrating and/or adjusting associated with the measurement process is possible without long interruptions of the measurement process, the predetermined concentration of the reference liquid is gained by mixing at least two standard, which contain different concentrations of the chemical substance.Type: GrantFiled: September 12, 2012Date of Patent: July 28, 2015Assignee: Endress + Hauser Conducta Gesellschaft für Mess-und Regeltechnik mbH + Co.
