What is ULTRON HF-C4
- The ULTRON HF-C4 column is capillary column that employ monolithic silica (hierarchical porous structure) bonded with C4 groups for high-precision separation analysis.
- Enables separation proteins that have not been enzymatically digested.
- Enables suppression of carry-over by deactivation treatment on the silica surface.
- Enables analysis of proteins under low-pressure condition.
- It can be expected to searching unknown components and simultaneous analysis of various proteins.
- The column inner diameter is 0.1 mm and can be used for nano flow LC system.
- Suitable for LC/MS that requires high sensitivity detection.
- The column is protected by a PEEK column jacket, making it easy to handle.

ULTRON HF-C4 Effect of column temperature (protein mixture)
In case the molecular weight is around 80 kDa, enables protein separation at temperatures close to body temperature.
ULTRON HF-C4 Column batch reproducibility (protein mixture)
Good reproducibility among column batches.
ULTRON HF-C4 Separation comparison with different column length (protein mixture)
Longer length columns achieve more defined separations.
ULTRON HF-C4 Effect of column temperature on mAb analysis
Enables analysis of mAb (145 kDa) at higher than 45℃.
ULTRON HF-C4 Effect of column temperature on mAb analysis
Since analysis can be performed at low temperatures (45, 50℃), generation of unknown components derived from mAb can be suppressed.
ULTRON HF-C4 Carry-over of mAb
The column has showed more than 85% recovery at 50℃ column temperature.
ULTRON HF-C4 Fitting
| Fitting | Remarks |

The outer diameter of the capillary column is 0.38 mm. Please use suitable fittings (Sleeve, Ferrules, etc.) for your Nano Flow LC system. Normally, FEP sleeve fittings are shipped as a standard specification. Pressure resistant fittings (Inlet side: PEEK sleeve) are also available as option with additional cost.
