Hello everyone, so I have a question...
For example, if you go in nature and pick some herb, is there a way to determine what molecules
are in that herb ?
Or if you want to test a pill and see what is in it?
Or you want to test a gold nugget and see exactly what is in it beside gold ?
Or if you want to know exactly what you are eating and you want to test
for example a piece of bread or a popcorn and see what chemical compunds, molecules are in it?
What are these devices called?
Are they very expensive ?
Are they accurate and will show every single thing thats in some material or are there molecules/atoms that could hide to such device?
