PrincetonSPHER-300 |
|
| |
 PrincetonSPHER-300
300Å pore size 5 µm spherical particles
HPLC columns. These are the columns of choice for
large molecules such as proteins and peptides. The
low surface areas of these packing materials are
beneficial for separations requiring low percentages
of organic modifiers.
In many applications PrincetonSPHER-300 columns
are equivalent to columns packed with Nucleosil
and Vydac.

PrincetonSPHER-ULTIMA |
|
| |
 PrincetonSPHER-ULTIMA
100Å pore size - 10, 5 and 3µm sherical
particles columns are prepared with a high quality
spherical silica that has been specially processed
to yield a homogeneous silanol environment for bonding.
Proprietary bonding chemistries applied to the specially
treated silica result in phases that can separate
basic compounds with excellent peak symmetries.
The polar imbedded functionality employed in the
bonded phase chemistries deactivates neighboring
free silanol groups and enhances the wetability
of the bonded ligands. Enhanced ligand wetability
makes the ULTIMA C18 column especially suited
for applications requiring straight aqueous mobile
phases.

PrincetonSPHER-OmniSEP |
|
| |
 PrincetonSPHER-OMNI [Non-collapsing C18 hydrocarbon phase] 100Å pore
size - 5 and 3µm spherical particles HPLC columns
feature novel stationary phases which does not collapse in straight aqueous mobile phases. The
OMNI columns are endcapped with a proprietary endcapping
reagent which imparts low pH stability and base
deactivation properties to the columns. OMNI
columns are excellent for a wide variety of applications.

PrincetonSPHER-HTS |
|
| |
 PrincetonSPHER-HTS
[High Throughput Screen] 60Å pore size 5
and 3 micron spherical particles HPLC column is
a new C12 phase developed for high speed analysis
and semi-preparative applications. The 60Å,
400 m/g spherical silica used for the stationary
phase support was selected to give sufficient capacity
for complex mixtures analyzed in the gradient elution
mode. The unique structure of the C12 ligand facilitates
rapid equilibration between gradient runs.

PrincetonSPHER-C27 |
|
| |
 PrincetonSPHER-C27
100Å pore size - 5 and 3micron spherical particles
is a proprietary phase containing a well-defined
and reproducible, branched-chain hydrocarbon ligand.
The structure of the C27 phase minimizes the folding
that can occur with traditional C18 phases, this
allows use with neat aqueous mobile phases. Retention
for most polar compounds, including hydrophilic
low molecular weight carboxylic acids, is enhanced.
PrincetonSPHER-C27 can be substituted for
C18 in most applications.

PrincetonSPHER-C30 |
|
| |
 PrincetonSPHER-C30
200Å pore size - 5 and 3 micron stationary phases
is bonded with a distribution of long chain hydrocarbons
that have an average length of C-30. This material
has been found to successfully separate many isomers
in the carotenoid family of long chain molecules.
Along with other large molecules such as proteins and peptides. This material has
good stability over a wide pH range.

PrincetonSPHER-PFP |
|
| |
 PrincetonSPHER-PFP
(Pentafluorophenyl) 60Å pore size 3 and
5 µm particles HPLC columns are
prepared with a high quality spherical silica. The
PFP column has been shown to be very effective in
separating natural products such as Taxol and related
Taxanes. The PFP columns is an effective
alternative to conventional Phenyl columns for difficult
separations. PrincetonSPHER-PFP HPLC columns
are useful for differentiating Halogen bearing compounds
from their non-Halogened analogs.

PrincetonSORB |
|
| |
 PrincetonSORB
125Å pore size 10 and 5 µm irregular particles
HPLC columns meet the criteria of economy, performance
and ruggedness. Princeton Chromatography is able
to offer these columns at modest prices due to proprietary
silica preparation and bonding techniques. Every
PrincetonSORB column is individually tested.
PrincetonSORB columns are excellent replacements
for columns packed with LiChrosorb, Econosil, Partisil,
Maxsil and Bondex packing materials.

 PrincetonSPHER-
FO (Fluorooctyl) 60Å pore size 3 and
5 µm particles HPLC columns are
prepared with a high quality spherical silica. The
Fluorooctyl columns is an effective alternative
to conventional Phenyl columns for difficult separations.
The Fluorooctyl columns are also effective in the
separation of natural products such as Flavanones
as well as Halogen containing aromatics. PrincetonSPHER-Fluorooctyl
HPLC columns are useful for differentiating Halogen
bearing compounds from their non-Halogened analogs.

PrincetonSPHER-60
- 60Å pore size 10, 5 and 3 µm spherical
particles HPLC columns are optimal for compounds
under 100MW. This high surface area media is base
for situations when high resolution is needed.
In most cases retention times will be longer than
with 100A material. All PrincetonSPHER
60Å columns are packed with an ultra high purity
silica media that is custom bonded at our facility
to ensure the highest standards of quality.
