Chromatography Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column BR-C18, 3 µm, 120 Å, 4 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.
YMC America, Inc TMS guard 120A 3um 10x4mm
YMC-Pack TMS columns are bonded with trimethylmonochlorosilane to create a phase with intermediate polarity This makes for a versatile stationary phase that is useful for analysis of extremely hydrophobic compounds using conventional reversed-phase solvents or highly polar compounds using high aqueous solvents The unique chemistry of this packing material is also well-suited for the analysis of multifunctional compounds Selectivity characteristics of a C1 bonded phase can be unique and samples must be evaluated to determine the applicability of the phase
YMC America, Inc C4-HG guard 120A 10um 30x10mm
YMC-Pack C4 is ideal for analyzing mixtures with a wide range of component polarity This is due to the C4 bonded phase exhibiting shorter analysis time while still maintaining high resolution when compared to longer-chain bonded chemistries YMC-Pack C4 (Butyl) columns are available with three pore sizes to accommodate optimum separations of virtually any molecular-weight compound The 120 phase is used extensively with non-polar peptides which are too strongly retained on C8 and C18 The 200 and 300 phase columns effectively resolve many classes of proteins and biopolymers

YMC America, Inc SIL-HG guard 120A 10um 30x10mm
The high-purity silica found in YMC-Pack SIL columns provides virtually complete sample recovery The absence of silica impurities reduces non-specific sample adsorption and the totally porous nature of the silica provides high sample loading The elevated chemical purity of YMC silica results in a particle structure exhibiting high mechanical strength YMC-Pack SIL is suitable for separation of fat-soluble compounds using non-polar mobile phases as well as the separation of positional isomers that are difficult to separate in reversed-phase mode SIL-06 (60 pore size) has greater adsorption properties than SIL (120 pore size) due to its larger surface area and is generally useful for separating natural products with low molecular weight
YMC America, Inc ODS-A guard 120A 10um 10x4mm
YMC-Pack ODS-A is a high-coverage fully-endcapped C18 phase which exhibits exceptional lot-to-lot reproducibility It is available in three different pore sizes and is suitable for the separation of a wide range of compounds YMC-Pack ODS-A in 120 pore size is used for high performance reversed phase separations It has selectivity for the separation of many organic compounds found in pharmaceutical chemical and biotechnology industries 200 ODS-A offers a unique mix of moderately large pores and high surface area for the analysis of compounds ranging from small organics and pharmaceuticals to moderately-sized proteins
YMC America, Inc Ph guard 120A 5um 10x30mm
Phenyl columns provide unique selectivity when compared to aliphatic straight chain reversed phase materials such as C18 C8 and C4 YMC-Pack Phenyl is a monomerically-bonded phenyl and is fully endcapped Typical applications include aromatic compounds phenols fullerenes sweeteners
