YMC America, Inc PRO C8 3UM 120A 20X2.1MM PK/5
OS12S03-02Q1GC: Pro C8, 3um, 120A, 20X2.1mm Cartridge, pk/5
Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, SRT SEC-1000, 5 µm, 7.8 x 50 mm, Light Scattering SEC
Utilizing proprietary surface technologies, SRT SEC phases are made of the uniform, hydrophilic, and neutral nanometer thick films chemically bonded on the high purity and enhanced mechanical stability silica. This proprietary surface technology results in excellent column-to-column reproducibility. The nature of the chemical bonding and the maximum bonding density of the thin film benefit SRT SEC phases with high stability and negligible non-specific interactions. Along with the widest pore size selection of 100, 150, 300, 500, 750, 1000 and 2000Å, SRT SEC packings have highest capacity that enables highest resolution.
YMC America, Inc SILICA 5UM 120A 20X2.1MM PK/5
SL12S05-02Q1GC: Silica, 5um, 120A, 20X2.1mm Cartridge, pk/5
Sepax Technologies Inc Sepax HPLC Column PolyRP-500, Guard cartridge with holder, 10 µm, 4 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Sepax Technologies Inc Sepax HPLC Column BR-C18, Guard cartridge replacement, NO holder, 1.8 µm, 120 Å, 2 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, BR-C18 bonded phases have been innovatively and specially designed to ensure maximum surface coverage and full end-capping, which leads to carbon content as high as 19.0%. The bonding chemistry is completely controlled that results in very reliable column-to-column reproducibility. The maximum surface coverage allows BR-C18 to have exceptional stability, resulting in high pH stability in the range of 1.5 to 10.5.
Sepax Technologies Inc Sepax HPLC Column Polar-Imidazole, Guard cartridge with holder, 3 µm, 120 Å, 2 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, Polar-Imidazole phase is bonded with imidazole functional groups. With a polar and N-containing ring structure, Polar-Pyridine phase is a weak base and adequate for many applications, such as pharmaceuticals, peptides, sugars, and nucleotides.
Waters Corp Nova-Pak Phenyl Sentry Guard Cartridge, 60Å, 4 µm, 3.9 mm X 20 mm, 2/pk
Nova-Pak HP Phenyl columns are based on 4 µm silica-based particle technology. The phenyl ligand is used to achieve unique compound selectivity with reversed-phase applications.
