HPLC mobile phase life - 2005/11/28 19:10
I think that greater than 20% organic of any common HPLC organic is surely biostatic and you could have extended expiration dates. I read someplace that 2% ACN, 10%MeOH, and 7%IPA were biostatic. We give all orgainic containing mobile phases a two week expiration and haven't had any problems. When doing standard and sample stability I also set aside some mobile phase and do one run with two week old mobile phase and make sure everything looks ok.
Amber bottles are useful for storing non-biostatic solutions like buffers without organic.
