what is the apparatus that allows me to identify any chemical element or molecule?

Question

i need it for a robot, should i use a polarimeter, a spectroscope, a refractometer? pls tell me

Answer 1

We can get the exact structure of a chemical element, by the observaton of its spectrum(UV or IR Spectrum), therefore you can use a spectrometer (IR is the better one), to identify a chemical element.

Answer 2

Methods for identifying genes which bind to natural products and other small molecules using a phage display system are described. Phage displaying protein which binds the target molecule are selected by affinity chromatography using a solid support to which a small molecule non-peptide bait is coupled. The selectively bound phage can then be amplified and the DNA inserts encoding the binding protein sequenced. The specifically bound protein is then useful to screen for therapeutic candidates which can then be used to treat conditions modulated by the target protein.

Answer 3

there is no machine that can identify *any* element or molecule unambiguously and without interpretation, but a spectroscope is your best bet for the widest variety of molecules.
