I agree with DR. The major issue with pharmaceutical analysis is that quality systems rule, OK!.
I recommend reading the ICH quality series guidelines, especially Q7, which defines cGMP for active pharmaceutical ingredients.
Although APIs are not directly related to medical devices, once you've finished that, you will have an excellent overview of the whole pharma quality process for active ingredients, and you can then look at some of the earlier Q series documents that cover specific aspects, and also those covering medical devices.

The other tome to investigate is the the current USP/NF ( which is expensive, but your workplace should have a copy somewhere ), especially the first section ( General Notices and Requirements ) and also the relevant sections of the General Chapters of the USP, denoted as <621> etc., near the back of the USP, but in front of the NF section.
The section titles are fairly self-evident but arranged according to test type, however the turgid text of some chapters is worth a cursory investigation, at least.
Congratulations, and good luck.
Please keep having fun,
