Hello,
I had maintenance done on my Agilent 1290 Infinity II UHPLC not too long ago and was informed that one of my deuterium lamp (part no. 2140-0820) replacements was bad. We buy lamps well in advance of when we need them, so they are there when we do need them, but that also puts them out of the 90 day warranty. These lamps aren't cheap. Do I just suck it up and buy a new one or has someone in my situation gotten a replacement somehow?
I feel like it is unreasonable to have to check all of my new lamps as soon as I get them, and in the box they have a certificate that is supposed to assure that all parameters of a good lamp are checked off.
Any suggestions would be greatly appreciated!
Note: The lamp would be less than a year old (they are replaced about every 6 months), and I have read that they shouldn't really have a shelf life here: https://community.agilent.com/technical/lc/f/forum/940/shelf-life-of-lamps.
