| Discovery BIO Wide
Pore C8 |
| Intermediate hydrophobicity between a C4/C5
and C18 makes it a great starting point for peptide method development.
Used for peptides and small proteins. |
| |
| Discovery BIO Wide
Pore C18 |
The most hydrophobic BIO Wide Pore phase. Excellent
for synthetic and natural peptides and peptide mapping.
Now in 0.18mm ID dimensions. |

Technical Bulletin:
Peptide Separations on a Stable, Aqueous-Compatible C18 Column
Most C18 HPLC columns undergo phase collapse in 100% aqueous mobile
phases with concomitant loss of retention. This causes a problem
when trying to analyze very polar compounds. This Technical Bulletin
describes how Discovery BIO Wide Pore C18 columns do not undergo
phase collapse, and can be used in 100% aqueous conditions. The
implications for polar peptides and peptides mapping is described.
