If you go to QC Physical and Chemical Group, you should master the detection methods in drug analysis, look at the detection operation specifications, and be familiar with high performance liquid chromatograph, gas chromatograph, polarimeter, ultraviolet-visible spectrophotometer, infrared-visible spectrophotometer and melting point instrument, mainly focusing on high performance liquid and gas phase, which are widely used. If you go to the biochemical inspection team, look at the knowledge of aseptic inspection, bacterial endotoxin, pyrogen and microbial limit inspection.

Look at GMP before you go to QA. It's easy to find on the Internet.

Do more, think more and ask less. Why do you ask a lot? If you don't understand something, you can ask and learn more.

Habit needs a process. Good luck with your internship.
