Abstract (en)

[origin: WO0140779A1] The invention relates to a device and a method for determining the quality, in particular the state of aging of fluids containing hydrocarbons which form radicals and peroxides in the presence of oxygen. A result on the state of aging of a given fluid can be obtained based on the determination of the presence of the content of peroxides in fluids in a chemiluminescence assay by means of a measuring and evaluation device.
