Abstract (en)

[origin: WO2012152514A1] The invention relates to a method for photometrically determining the uric acid and creatinine content of a liquid, particularly of a dialysate as a control variable in a haemodialysis treatment. The liquid is irradiated with UV radiation at three wavelengths in the range between 235 nm and 300 nm, and the radiation absorption in said liquid is measured at these predetermined wavelengths, a first of which lies in a sub-range between 235 nm and 250 nm, a second lying in a second sub-range between 255 nm and 270 nm, and a third lying in a third sub-range between 280 nm and 300 nm. The uric acid and creatinine contents, and optionally the content of a third component, are calculated from the results of this measurement.
