The SDA or Surface Dust Analyser that flew on the probe past those moons
was equipped with a micro miniature TOF mass spec. They analysed ice
particles caught on the sensor surface for composition.

Or in much more detail:

It is a very cunning design and out in space they already have a vacuum!
It doesn't produce coffee table book pretty pictures so its experimental
results are largely (totally?) ignored by the popular press.

From what I understand reading Wikipedia, SUDA hasn't been used in
space yet and previous missions used other, but similar devices. The
Cassini CDA and Stardust CIDA are mentioned. According to NASA[0],
the Europa Clipper will be launched in 2024 carrying the SUDA.
