3.1 Preparations (implementingArticle 4.1 of BG6541) Clean the sample cup with
petroleum ether, then wash with acetone and water respectively, and then wash with
hot chromic acid lotion to remove oil stains, and finally rinse with water and distilled
water. If the sample is not used immediately, it should be poured into a clean On the
cloth. Clean the platinum ring with petroleum ether, rinse with methyl ethyl ketone,
and heat it in the oxidizing flame of an alcohol lamp. Note: To clean the platinum ring,
it should be removed from the rod of the ring frame. When removing and installing
the platinum ring, be sure to handle it gently.After installing the platinum ring, make
sure that each part of the platinum ring is on the same plane (Figure 5). ). Hang the
cleaned platinum ring. Pour pure water into the clean sample cup to the middle scale
