They are available from some of the manufacturers of optical emission spectrometers, portable units that use optic fibre links between a hand-held arc unit and the data capture/processing unit.

I believe that using such equipment is the only way you will be able to distinguish the two grades on-site. You simply have to do a chemical analysis of each piece and see what the actual carbon content is in each case.
