[IB] NASA Invents New Technique For Finding Alien Life.

By adding a laser and an ion funnel to a mass spectrometer, it is possible to analyze the elements from the Martian surface directly, without the complex handling samples usually need.

The mass spectrometer is used to identify molecules, their elements and their isotopes in samples ranging from rocks to proteins. It does so by looking at their mass-to-charge ratios. Ordinarily a sample has to be prepared because it will be vaporized and then ionized so the electrons and atomic nuclei can be separated.

The new version uses a two-step technique. First it shoots a laser at the sample's surface. This creates a plume of molecules and ions. To get the ions into the mass spectrometer, the new system uses an ion funnel. The ion funnel uses conductive, progressively smaller electrodes in the shape of a ring that attract the ions, effectively vacuuming them into the mass spectrometer.
Let this be a lesson to all of you.

Lasers make everything better

Mass Spectrometry. Meh.
So annoying to write an essay about...

Is that a frickin' rover with a frickin' laser beam attached to it's frickin' head?

This sounds awesome. I can't wait till I can just put a sample on a slide and get a elemental analysis in minutes. Could make protein analysis cheaper as well. I wonder how they keep it contaminant free?
