PrincetonSPHER C30 is designed for separation of carotenoids and closely related species in reverse phase. C30 works well for positional and stereoisomer separation. PrincetonSPHER C30 is extremely reproducible and versatile. Pore size is 200Å.

PrincetonSPHER C8-ZX is a replacement for Zorbax C8

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.
