... and in any lab, especially if you haven't got things like that for cleaning, guard your clean bottles jealously. I don't share with the department's washing up. My bottles are labelled separately and rinsed without soap.

hi,

I have a new problem today (its just not working for me this week!). Phthalate contamination peak at 391 up to 3 x 10^7 ion count. I know how i got it, while rinsing the bottle before transferring fresh mobile phase, I capped it and shook the bottle containing MeOH.. silly and costly mistake...

Any one has any idea how I can get rid off it from the HESI MS??

Best way to clean the mobile phase bottles for LCMS is using a muffle furnace at about 550C. It will burn out all the organics in a few hours and you have a nice shiny clean bottle after. Just make sure you are using Pyrex, Kimax or Schott bottles so they don't soften at those temps.

HI

Thanks for that, but we dont have access to a muffle furnace. I have one bottle which is contaminated and I plan to get rid of it. Any ideas on how to get it out of the HESI system?
