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 |
|
|

| 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. |
