Ultimasyil C8 120Å Columns ,
| Stationary Phase | C8 (octyl) bonded silica; Reversed phase, moderate hydrophobicity (less than C18) |
| Pore Size | 120 Å |
| Silica Purity | Very high purity silica (~ 99.99 % SiO₂) |
| End‑Capped | Yes; to reduce silanol activity, improve peak shape |
| Typical Particle Sizes Available | Multiple; NCI offers various particle sizes (2, 3, 5, 7, 10 µm) for their stationary phases. |
| Phase Type (USP code) | L7 (C8) for reversed-phase classification |
| pH Range / Stability | Given typical C8 columns, reasonable pH range (usually ~2‑8) unless special bonding; but for exact allowed range, one must check with NCI datasheet. Not all details found for the C8 version specifically. |
