Chaos, it's not just a theory, it's life

The point of having two identical analyzers on the chemistry line is not only to split the workload for a faster turnaround time, but also as a backup so that if one goes dow, you can load to the other as a backup. BOTH are NOT supposed to go down at the same time. We have two LX20 analyzers on the chemistry lab. We were having trouble with chlorides and BUN's on number one throughout the day, so we were keeping a close eye on that when number two just totally froze up right as we were taking number one down to fix the chloride problem. Problem: No working analyzers for electrolytes and a whole bunch of other tests for at least 20 minutes because #2 has to be shut down and rebooted, and rebooting takes at least 10 minutes by itself. So as that one is getting shut down, I'm putting #1 into maintenance mode so that I can tear out the new chloride electrode that was acting up and put the old one in that was working fine. I had the electrodes switched in 5 minutes, and by that time #2 was back up again. But then the BUN reagent had to be changed because that was acting up and we had a new lot number, so why not just change that? So that was done. Then came the calibration. I just crossed my fingers and prayed that chloride and BUN would calibrate and they did and then the controls were in, so all was good. But why can't this stuff happen AFTER I go home?
