Very close to the 'tricorder' in star treck.

What I have is a portable device to measure biological molecules," he said. "If you were at an airport and found a white powder you're going to want to know if it is anthrax or chalk dust fairly quickly.
beats taste test :P
To an oldie and technically literate even things like this are astounding but in reality are predictable

The prototype looks promising but still has a long way to go. 13 kilodaltons isn't sufficient to cover significant range of macromolecules relevant to celullar processes.

Isn't there already one of these in Space - well on the surface of Mars.

It sounds very similar to the mass spectrometer the Open University developed for the ill fated Beagle2

probably a mass spectrometer for small molecules and not for biological macromolecules

I think that there was life on mars and could possibly still be some kind of life existing today.
