Synthetic air O2/N2
Argon: Argon is used, primarily in liquid form, as the target for direct dark matter searches. The interaction of a hypothetical WIMP particle with the argon nucleus produces scintillation light that is then detected by photomultiplier. As with most other liquefied noble gases, argon has a high scintillation light yield, is transparent to its own scintillation light, and is relatively easy to purify.
