Purity Monitors for Liquid Argon

In this video, I explain a project I've been working on for the past two years: purity monitors for liquid argon. These devices are able to measure the purity of liquid argon (-186 C) to very low levels (they are sensitive to a few tens of oxygen molecules every one trillion atoms of argon). In the past few weeks, together with colleagues at UCL, I have been installing two purity monitors in the protoDUNE dual-phase at CERN. Please, leave your feedback and any question you might have. If you like the video, give it a thumb up:)
