Re: [MW:23458] PMI vs Chemical test

Hi

Typical methods for PMI are XRF and OES (both portable methods). 

XRF is more qualitative than OES and could not be used for C, S & P measurement (Its weak point is measuring light elements)

Portable OES (with spark method) has ability to measure C more accurate compare with XRF and less accurate compare with Stationary OES, but has same situation for S & P.

My experience says, after calculation of carbon equivalent if you got a number near the criteria ( about 0.01 or 0.02% below or above it) do not rely on portable OES results.

Dear Jay

We cant replace chemical test with PMI.

We cant get the carbon equivalent with the help of PMI.

Dear Experts,

Is PMI replacement for chemical test. With PMI can Carbon equivalent be known?

Kindly advise
Thank you
