I just wanted to get a general idea of on average, how long your columns last...
I have a Luna C18 that I use daily for sunscreen analysis with an 85:15 MeOH:0.1% TFA MP. It appears to have reached its end, rather suddenly I might add. This is my second column and the performance is very good. But I was just curious to know the column lives for some of you out there.
Obviously the life is dependent on the type of sample, mobile phase, etc., but I wanted to see what lengths of time of usage some of you are getting, so I could compare.
Thanks!
