Ordering Information

Discovery HS C18 HPLC Columns, 120Å;
3µm, 5µm and 10µm particle sizes available
 

Specifically developed for pharmaceutical analysis and purification

Ideal for LC/MS applications - No detectable bleed (as independently tested)

Highly stable to ensure excellent run-to-run and lot-to-lot reproducibility and long column life

Scalable from analytical to prep


Here's the
Proof
 
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)

 

Competitor C18

TIC Baseline rise can interfere with sensitivity, and quantitation measurements. Bleed m/z peaks could coincidently interfere with "real" peaks.
