"Ultimasyil Amino Preparative 100 Å" —an amino‑phase HPLC column with a 100 Å pore size.
Stationary Phase & Material
Crafted from spherical, totally porous, ultra‑high purity (>99.999%) type B silica, these columns receive a proprietary surface modification before bonding to produce a smooth, uniform surface with fewer acidic silanol groups.
Particle Size & Pore Size
Available typically in 3 µm, 5 µm, and 10 µm particle sizes. The reported surface area for the 120 Å version is around 320 m²/g, though a 100 Å pore size (as mentioned in your query) is plausible given typical amino columns, and aligns with standard practice in amino‑phase packing.
Phase Type & USP Classification
These are amino (aminopropyl) phases used for reversed-phase or normal-phase separations of amino acids. Their USP classification is L1, indicating a normal-phase or polar stationary phase.
