Hello everyone! I'm a highschool student and it was just recently since I started learning about Arduino (for my science class). Can you please help me by suggesting what kind of sensor should be use to measure the presence of heavy metals, detergents, pesticides, hydrocarbons, inorganic acids, and …

A mass spectrometer would be a good start, it will pick up at least most heavy metals and possibly even the radioactive ones (as long as they have a unique atomic mass, not overlapping with other minerals, in which case you have to do other forms of separation first). IR absorption spectra are grea…

A mass spectrograph would do the job quite decently.
