Orosil Polar C18 Orosil Polar C18 columns are particularly advantageous for difficult separations involving polar and semi-polar compounds. Excellent selectivity for polar and semi-polar compounds Superior separation of basic analytes High hydrophobicity Strong polarity Available Phase: C18 Particle Sizes: 3, 5, 10, 20, 50 µm Surface Area: 190 m 2 /g Pore Size: 90 Ǻ Pore Volume: 0.55 using a Orosil Polar C18 Column
Reliasil Reliasil HPLC columns are designed for high efficiency (high plate count) and general utility. The proprietary silica gel manufacturing process yields a Gaussian particle size distribution, narrow pore-size distribution, and strong resistance to high ph. Preferred by many chromatographers for its chemical stability and effectiveness in the reversed phase separations of peptides, pharmaceuticals, and derivatized amino acids. Reproducibility Excellent mechanical and chemical stability Superior efficiency Wide variety of phases Rugged, general-purpose support Available Phases: silica, C1, C4, C8, C18, NH 2, CN, phenyl, SCX, and SAX Particle Sizes: 3, 5, and 10 µm Surface Area: 190 m 2 /g Pore Size: 90 Ǻ Pore Volume: 0.55 ph Range: 2-8.5 Separation Of Neutral Analytes using a Reliasil ODS-2 Column using a Reliasil ODS-2 Column 1. Ethyl Benzoate 2. toluene 3. ethyl Benzene
Prestige Prestige is Orochem Technologies next-generation of highly base-deactivated stationary phases. Double end-capping and narrow particle size range contributes to superior basedeactivation and low backpressure. Highly base-deactivated (double end-capping) Narrow particle size range Low backpressure Separation of Neutral Analytes 1. Ethyl Benzoate 2. toluene 3. ethylbenzene Available Phases: C18 and C8 Particle Sizes: 3, 5, and 10 µm Surface Area: 320 m 2 /g Pore Volume: 0.9 ph Range: 2-8.5 Separation of Basic Analytes Separation of Polar Analytes 2. pyridine 3. phenol
Matrix Matrix C18 uses base-deactivated, ultra-high purity silica gel, densely bonded to produce an inert material ideally suited for the analysis of basic compounds. The resulting hydrophobic surface is also stable over a wide ph range (2-9) to allow for excellent method flexibility. Matrix C18 AQ has been specifically designed for the analysis of polar analytes in high aqueous mobile phases. Matrix C18 AQ features the traditional C18 groups interspersed with hydrophilic end-capping groups. The resulting material is easily wettable and, unlike conventional C18 materials, does not exhibit retention loss in high aqueous conditions. Ultra-high purity silica C18 AQ version for high aqueous conditions Available Phases: C18, C18 AQ, C8, and NH 2 Particle Sizes: 3 and 5 µm Surface Area: 300 m 2 /g Pore Volume: 0.95 ph Range: 2-9 using a Matrix C18 Column
