Actually, a mass spectrometer is a device that measures a spectrum
of molecular or atomic mass.

You also shouldn't confuse mass spec with mass general. That's a
hospital in Boston.

Son, I have an MS from MIT, so don't tell me what a mass spectrometer is.
The journalist who said Spirit had it was simply wrong. Mass General is
where I had my knee operated on, Mass Ave. is how you get to Harvard, and
Mass Pike is the site of the "Big Dig."
