oxygen spike

my group has never been as happy to see an oxygen spike on the glove-box as we were yesterday. usually, we like to keep the count down to 15 ppm oxygen or less, but sometimes when we bring things into the box the number skyrockets (once to 700…not fun to fix – purging can take hours).

lately, we’ve had a run of good luck, and the count has stayed extremely low (hovering at and below 1 ppm). in fact, we’ve lately started to worry that the box was lying to us and the oxygen analyzer was actually broken (chemists: suspicious of labs going well). yesterday, though, when we brought in a slew of things from the large antechamber, the count spiked to around 50 ppm – to much rejoicing. i’m just glad i made sure to cap off my experiment. though it’s a color it isn’t supposed to be, i’d rather not corrupt it any more than it already is.
