NOTE: Never touch test strip with bare hands during or after final polishing or allow strip to come into contact with water. 8 Polish first the ends and then the sides with 150-grit (mesh) silicon carbide grains picked up with a pad of absorbent cotton moistened with isooctane. 9Polish strip uniformly using long strokes that carry beyond the end of the copper strip. 10When strip is clean, with minimal delay, slide copper strip into sample tube. 11Place sample tube into pressure vessel and screw lid on tightly.
