Hi everyone,
I am looking for a used XRF machine for oil debris analysis. New prices are over the moon.

To detect the difference between gear and bearing steel it seems the Cr % is the way to go. Any thoughts ?

What happens if the sample has 90 gear particles and 10 bearing particles, will it read a Cr value close to gear steel ?

What options do I have to answer the source question with certainty ?

Cheers

John
