Abstract :
CHEMICAL TREATMENTS in porous carbon blocks from which brushes are to be fashioned often are distributed unevenly so that the final brushes do not contain the calculated percentage of treatment obtained from weight relations. In order to analyze the treatment quantitatively under small individual areas, a practically instantaneous, nondestructive method of treatment has been applied which makes use of an X-ray absorption photometer.
