I think many of us still "groan" when we think of WEEE/RoHS. However, as I have mentioned before, whenever there are radical changes, oppotunites abound. Consider what Frank writes:
Has anyone found a steel mill willing to certify steel for sheet metal as RoHS compliant?
Apparently no one tests melts for cadmium content.
As you may remember Cadmium must be below 0.01% in homogeneous material. This concentration is is only 100ppm, so it is difficult to analyze with fast techniques like x-ray fluorescense, However, atomic absorption spectrometry, a relatively common technique, should work nicely.
What an opportunity! Be the first steel mill to test for this an you get all of RoHS related the business.
