Yes. Quality Control is concerned with, for example, specifications -- for example, a final product must have a certain pH +/- a certain range, as determined by an autotitrator, according to procedures listed in an SOP. Quality Assurance would specify, for a group of products, including the product above, that the reported result be consistent across all products, and that QC SOPs and individual product documents are consistent. The Total Quality Management would oversee a consistent policy and SOP's for Quality Assurance, as part of the companies overreaching stated goals.
It gets complicated rapidly -- I have worked at companies that produce fine chemicals where QC and QA were essentially the same people. If I describe that situation to pharmaceutical manufacturers, they tend to almost fall out of their chair, they're horrified by the concept -- it seems like too much conflict of interest. Which it would be, for something people consume when they're sick, but not for a bulk chemical reagent.
