HALO Penta-HILIC is the latest addition
to the original 2.7µm range of Fused-Core columns manufactured by Advanced
Materials Technology. HALO columns feature a 0.5µm porous silica layer ‘fused'
onto a 1.7µm solid silica particle. The resulting columns provide faster
separations and higher sample throughput, without compromising column
efficiency, ruggedness and reliability. These Fused-Core particles generate
significantly lower back pressure compared to other UHPLC columns, enabling
them to be used with conventional HPLC as well as UHPLC equipment.
The proprietary penta-hydroxy containing ligand of this
new HILIC phase creates a highly polar bonded stationary phase compatible with
all typical HILIC operating conditions. The fast column equilibration obtained
is especially useful for gradient separations.
HALO Penta-HILIC columns show excellent peak shapes for
polar compounds containing a variety of functional groups:
- Acids,
bases and zwitterions
- Strong
and weak acids and bases
- Peptides,
sugars, nucleobases, nucleosides, nucleotides and derivatives
HALO 2.7µm columns are also available in eight other phases:
- C18
- C8
- HILIC (unbonded silica)
- RP-Amide
- Phenyl-Hexyl
- PFP
- ES-CN
- Peptide ES-C18 phases
..... and now NEW HALO-5 5mm Fused-Core HPLC columns available in C18 and PFP phases
New HALO-5 5mm HPLC columns are based on the same proven
Fused-Core particle technology as the original 2.7mm
columns but have been developed by fusing a 0.6µm porous silica layer on to the
surface of a 3.8µm solid core particle.
HALO-5 columns are initially available in C18
and PFP phases and have been specifically developed in order to provide
improved HPLC performance when used with traditional HPLC equipment, as the lower
back pressure of these columns is ideally suited to these instruments. It has
been demonstrated that for a given operating pressure, HALO-5 columns deliver
significantly higher efficiency than a column packed with 5mm
totally porous particles.
Key features of HALO-5 columns include
- High efficiencies at fast flow rates
- Low back pressure well suited to traditional HPLC instruments
- C18 and PFP phases
- Scalable from UHPLC separations developed on 2.7mm HALO columns
