Short summary
A common way of measuring trace gases in the atmosphere is chemical ionization mass spectrometry. One large drawback of these instruments is that they require radioactive ion sources. In this work we demonstrate a simple ion source that uses a small krypton lamp that can be used to replace a radioactive source.
