The product range is as follows
List of Application sheets
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.
- Small pore size yields high surface area of 500 m2/g
- Excellent resolution for your toughest separations
- Unique selectivity and retention characteristics as compared to common offerings from our competitors
- Use for compounds under 1000MW
- Largest variety of 60A column choices on the market today
- Optimized for long column lifetimes

PrincetonSPHER-100
PrincetonSPHER-100 columns are our most versatile. 100A media is extremely common in the marketplace, but PrincetonSPHER-100 can stand above the rest. With excellent batch to batch reproducibility and a large variety of phases, its hard to go wrong with these columns.
- Average surface area of 325 m2/g
- Extremely versatile
- Excellent for method development or replacement in an existing method
- Ultra high purity silica gel
- In stock and ready for delivery in two days or less
- Can be used as an equivalent to Phenomenex Luna, Waters Symmetry or YMC ODS-A

PrincetonSPHER-300
- 300Ĺ 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
- 100Ĺ 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-Omni
- Non-collapsing C18 hydrocarbon phase
- 100Ĺ 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
- For High Throughput Screening
- 60Ĺ pore size 5 and 3 micron spherical particles HPLC column
- New C12 phase developed for high speed analysis and semi-preparative applications.
- The 60Ĺ, 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
- 100Ĺ 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.
