Description
Detection principle
Catalase can decompose H2O2 to generate H2O and O2, the residual H2O2 in the detection system react with the fluorescent substance, and the content of residual H2O2 is proportional to the fluorescence intensity at the excitation wavelength of 535 nm and emission wavelength of 587 nm, the catalase activity is inversely proportional to the fluorescence intensity.

Dilution of sample
It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the pre-experiment and the detection range (0.01-6.51 U/L).
