HALO
Hyper-fast, super rugged HPLC columns
The fused-core* particle technology was specially
developed to produce hyper-fast chromatographic separation while avoiding
the uncertainties associated with UHPLC. The father of the technique is dr.
Jack Kirkland, widely regarded as one of the "founders" of HPLC.

Chemistries
C4 ...
The
world’s first 2.7-micron superficially porous silica particles with 1000
Angstrom pores for the separation of very large molecules such as monoclonal
antibodies, large proteins, synthetic polymers,
etc.
C8 ...
Separations are due primarily to hydrophobic interactions and differences in
hydrophobicity among analytes. Excellent for a broad range of analytes.
C18 ... Separations are due
primarily to hydrophobic interactions and differences in hydrophobicity
among analytes. Excellent for a broad range of analytes.
Peptide ES-C18 ... Ideal for
ultrafast and high resolution separation of peptides and polypeptides (≤
15 kDa). Enhanced stability at low pH via sterically protected ligands up to
90 degrees C.
Phenyl-Hexyl ... Separations
occur due to hydrophobic and pi-pi interactions. Enhanced retention and
selectivity for aromatic and unsaturated analytes (especially those with
electron-withdrawing groups and halogens). Compatible with highly aqueous
mobile phases.
HILIC ... Can be used in both
HILIC and normal-phase modes. Enhanced sensitivity and peak shape for LC-MS
analyses of basic analytes.
Penta-HILIC ... Provides
superior retention to silica HILIC and amide HILIC phases for acids and
zwitterionic analytes
PFP ... Separations take place
due to multiple types and degrees of analyte interactions including
hydrophobic, pi-pi, dipole-dipole, and hydrogen bonding. Can be used in
HILIC mode (with more than 80% acetonitrile in mobile phase). Enhanced
selectivity for stereoisomers. Compatible with highly aqueous mobile phases.
RP-Amide ... Retention and
selectivity due to hydrophobic and hydrogen bonding interactions. Less
retentive than C18 and C8, except for analytes with proton-donor groups.
Compatible with 100% aqueous mobile phases.
Peptide ES-CN ... Provides strong
dipole-dipole interactions with analytes and weak hydrophobic interactions.
Suitable for use in reversed-phase, HILIC, and normal-phase modes. Rapid
equilibration with low bleed for high throughput LC-MS applications. Extra
stable bonding with sterically protected ligand provides improved stability
and performance compared to conventional CN phases, especially at low pH
(1-4).
