- Scalable from analytical to prep
NO DETECTABLE LC/MS BLEED
Discovery HS C18
No TIC Baseline rise.
Essentially no m/z peaks generated from column ("x" indicates peaks also found in blank run)
Column: Discovery HS C18 and Conventional C18, 5cm x 4.6mm, 3µm;
0.1% TFA; Flow Rate: 1mL/min; Temp: ambient, esi+ ion.
Competitor C18
TIC Baseline rise can interfere with sensitivity, and quantitation measurements. Bleed m/z peaks could coincidently interfere with "real" peaks.
Mobile Phase: 15 min. gradient from 0-100% MeOH in
(work conducted by Dr. Shane Needham, Alturas Analytics, Moscow, ID)
