No Therapist Quests after Sanitary Standards pt1

I didnt get any further quests from Therapist after completing Sanitary Standards Pt1. I already had the Gas Analyzers and handed the one over right away but might not have been high enough level to get the follow up quest straight away, so idk if that caused problems or not?

EDIT: Apparently you have to finish Operation Aquarius 2 aswell for further quests (which I think isn't usually the case, at least Tarkov Wiki says that this isnt a prerequisite for it)
