How many HC is a catalytic converter supposed to burn?

Online there is no information at all about how much HC a catalytic converter is supposed to convert, so my question is out of a 1,000000 how much HC on average does a catalytic converter burn. or is this a question that is closely guarded. I know to Much HC is not good for the cats but what is the normal amount. Usually the only way to tell if the catalytic converter is getting to much fuel or HC is to test the NOX i don't have the gas amount information so i will have to test the NOX alone at a smog station, Because for the ML320 NOX is not testable to pass smog there for smog stations don't test the NOX at all.

What's not a secret is that your ability to find information on the internet is sorely lacking. There's plenty of info out there.
