- (Minimum of 200 words) Design a plausible procedure for QA/QC to follow for a typical product line at Acme, such as DMBTFE. Use the process outline from problem set 2 as a description of the raw materials needed. Assume that DMBTFE is a white, crystalline solid that is stable to air and water, and of only low toxicity.
