Experimental characterization of elastomeric O-rings as reusable seals for mass spectrometric measurements: Application to in situ K–Ar dating on Mars

•Vacuum sealing capability of elastomeric O-rings is tested for in situ K–Ar dating.•Argon blanks are measured and compared with signals from potential targets.•Viton O-rings achieve the blank-to-signal ratio of
