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.

PrincetonSPHER-100 PFP has novel selectivity for reverse phase applications and often is a strong alternative to traditional Phenyl or alkyl stationary phases. Pore size is 100Å.

PrincetonSPHER-100 Phenyl, our most popular Phenyl, 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.
