Ultra HPLC Columns The Ultra line represents Restek&rsquos broadest selection of stationary phases on a single silica support. Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, these columns are designed

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or &ldquocore-shell&rdquo particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column

Brownlee Spheri-10 C18 is based on a small pore silica, mono-functional, optimized for separating small molecules.

For reversed-phase separation of analytes with moderate hydrophobicity, use Thermo Scientific&trade Acclaim&trade 120 C8 LC columns. These high-performance columns provide selectivity that is similar to Acclaim 120 C18 columns with a predictable

Improve the separation efficiency in your reversed-phase applications with Thermo Scientific&trade Acclaim&trade 120 C18 columns. These columns feature an ultrapure silica substrate with extremely low metal content to minimize tailing effects and

Viva HPLC Columns: 3 or 5 &microm particles 300 &Aring pore size Excellent for separating peptides or proteins Rugged, spherical particles with 300 &Aring pore size High proportion of pore/surface area available to large molecules Viva columns

The choice of columns for analysis of difficult compounds by HPLC YMC-Pack Pro C18 columns start with a tightly controlled, highly purified silica gel, followed by a high-coverage C18 bonding and finish with a unique endcapping procedure utilizing

All phases in the Pro-family are ideal for the analysis of all types of organic molecules but specifically basic and metal chelating compounds. The ultrapure silica and very low residual silanol activity means that these columns frequently do not

ODS-AM is a high carbon load C18 packing that is similar in selectivity to ODS-A. The major difference between these bonded phases is that ODS-AM has extremely tight specification criteria which provides excellent peak shape and more reproducible
