Hello everyone,

I'm going to acquire a new LC-MS system for analytical (mainly) purposes. I am going to attend two demos in order to evaluate both the most recent shimadzu HPLC-single quad. detector and the Waters single quad. detector.

my question is if there is someone who can advice me about their performances and easiness of maintenance; in particular in terms of ability to clean (and/or) keep the mass detector clean thus avoiding contamination of the source. is there someone who has a direct experience on these two brand?

thank you so much for your help

best regards
Alb.
