Re: Quality and Purity

08/08/2011 12:54 PM

I hope others have given you a feel for the meaning. In some cases, they are totally unrelated.

Rolls Royce makes a quality car. How does purity apply at all in this case?

A chemical may be near 100% purity, but if it does not meet the required physical specifications (say granule size or bulk density) it is of poor quality.
