Another of my long term projects, trying to maximize my profits from catalytic converters, as you all know I de-can all my catalytic converters then mill the comb and bead into powder.
My drum is approching the half way mark to being filled, as soon as that compressor motor arrives I have another 75 cats to mill then I'll be sending in my first samples for an assay to see where I stand with this project.
The type of assay is ICP which costs around $500.00 for 3 elements, platinum, palladium and rhodium so its not likely that I'll be sharing the results from my assays unless someone wants to anti up and share the cost.
To be reasonable I would consider offering a copy of my assay for a small fee with a non disclosure agreement.
Once the assay is returned to me, I will give my opinion freely on weather it is worth the effort to de-can and mill your own catalytic converters.
Edited to add, assays report parts per million - if the assay report showed that you 1 ppm this would indicate that your material contains 1 gram per metric ton.
ICP-OES Inductively coupled plasma optical emissions spectroscopy is a major technique for elemental analysis.
The sample to be analyzed, if solid, is normally first dissolved and then mixed with water before being fed into the plasma. Atoms in the plasma emit light (photons) with characteristic wavelengths for each element.
This light is recorded by one or more optical spectrometers and when calibrated against standards the technique provides a quantitative analysis of the original sample. ICP instruments comprise of various optical spectrometers, nebulizers, spray chambers, ICP torch and RF generators.
