PrincetonSPHER Fluoropropyl is primarily used for separation of fluorinated compounds.

PrincetonSPHER HILIC is a specially developed stationary phase for use in methods requiring HILIC mode of separation.

PrincetonSPHER HILIC-PRO is a novel stationary phase for use in methods requiring HILIC mode of separation. HILIC-PRO offers alternate selectivity to our traditional HILIC material. HILIC-PRO is good for separation of basic compounds, especially those containing nitrogen heterocycles.

HTS is a C12 phase based on Adamantane, which is a cage-like structure that remains more rigid than traditional long chain alkyl ligands under reverse phase conditions. HTS is well suited for high speed gradient analysis, where fast reequilibration is necessary. HTS also performs well in 100% aqueous environments.

Ultima C18 is a polar embedded amide stationary phase and offers extended selectivity in comparison to traditional C18. ULTIMA C18 shows longer retention of very polar compounds and is compatible with 100% aqeous mobile phases. Pore size is 100Å.

Aminopropyl groups bonded to silica. Pore size is 100Å.

PrincetonSPHER-100 C18, our most popular C18, is bonded on ultra high purity spherical silica. With a pore size of 100Å and an average surface area of 325 m2/g, these columns are perfect for method development or as equivalent columns in existing methods. Excellent batch to batch reproducibility and 25 years of bonding experience make this phase a great choice if you are looking for consistency and quality.
