ULTRON HF-C4

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
Standard specification
(FEP sleeve)
① 1/16” PEEK plug
② 1/16” O.D. x 0.35 mm I.D. x 40 mm FEP sleeve
③ 1/16” CTFE ferrule

・ When installing the column to the system, tighten the column using a wrench (0.6 N.m as a guide).
Pressure resistant specification
(Inlet side: PEEK sleeve)
① 1/16” PEEK plug
② 1/16” O.D. x 0.41 mm I.D. x 40 mm PEEK sleeve
③ 1/16” PEEK High pressure ferrule
(Hybrid type of stainless steel and PEEK blended polymer)
④ 1/16” PEEK fitting
・ The above fittings corresponds to the VICI valve (ex. UltiMate 3000 RSLCnano system).
・ When tightening the ferrules use a wrench (1.4 N.m as a guide).
・ When installing the column to the system, tighten the column using a wrench (1.1 N.m as a guide).

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.
