New Dimension in Chromatography - Halo® 1.5

The HALO® BIOCLASS peptide columns and phases are specifically designed to offer selectivity, stability, and reproducibility to address complex peptide separations.

Excellent options for both fast and high-resolution UHPLC separations, HALO® delivers high peak capacity and is extremely stable at high temperatures and low pH. For peptide characterization, the optimized 160 Å pore size is ideal for small protein fragments and peptides.

HALO® BIOCLASS peptide columns deliver:

  • Optimized 160 Å pore size on a range of chemistries ideal for peptide analysis
  • Ideal for both ultrafast and ultra-high-resolution separations of peptides and polypeptides up to 20 kDa
  • Approximately 20% higher peak capacity than sub-2 µm non-core columns at comparable back pressure (2 µm)
  • Extremely stable at high temperatures and low pH
  • Columns of 2.7 and 5 µm can be used in series for ultimate in peak capacity of complex tryptic digest samples

BEST USES

Multiplexing in series for added peak capacity, lowest back pressure delivery.

BONDED PHASES

ES-C18, ES-CN

POWERFUL MULTIPLEXING

base peak mass chromatogram

In this example, two 0.2 x 250 mm HALO® 160 Å ES-C18, 5 µm nanoscale columns were connected in series to provide additional resolving power for LC analysis of the tryptic digest of reduced and alkylated trastuzumab.
