Hi, All,
I got batches of sample which came from converter catalyst of cars. Normally it will contain Rh, Pt and Pd inside the ceramic converter. We used the Nickel Sulfide method to fusion the samples in lieu of the traditional lead oxide method which has the poor recovery on Rh. Since we did some lots, the reproducibility is not very good and not in consistence. This is our first trial.
Therefore, I would like to ask is there any reference which I could refer to regarding on processing, sampling for car converter catalyst? or any suggestion and tips on analysis we could improve in Nickel sulfide fusion method? or any better analysis method for converter catalysts? Thanks a lot.
