YMC America, Inc Triart Phenyl 120A 5um 20x3mm
YMC-Triart phases are based on organic/inorganic hybrid particles that combine the high mechanical stability and efficiency of a silica-based packing material with the robust chemical stability of a polymer-based packing material This versatile resin is produced using tightly controlled particle formation technology adapted from micro-reactor technology The resulting uniform particle and pore size distributions as well as the smooth surface greatly contribute to excellent peak shape and separation reproducibility In addition YMC-Triart materials are highly resilient and robust when used at extreme pH elevated temperature and high pressure
YMC America, Inc YMCbasic guard 3um 10x4mm
YMCbasic is a unique reversed-phase column designed for analysis of pharmaceuticals and basic compounds Innovative silica synthesis and state-of-the-art silane bonding result in a chromatographic material with neutral silanols This minimizes interactions with both basic and acidic compounds
YMC America, Inc C4-HG guard 120A 10um 50x30mm
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 ODS-AHG grd 300A 15um 50x30mm
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

Sepax Technologies Inc Sepax HPLC Column Bio-C4, 3 µm, 300 Å, 4 x 10 mm
Monomeric and fully endcapped Bio-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. Bio-C4 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of intact proteins, and natural and synthetic peptides.
Sepax Technologies Inc Sepax HPLC Column Antibodix WCX, NP10, Guard cartridge with holder, 2 x 10 mm
Antibodix columns are specially designed for high resolution, high efficiency and high recovery separations of antibodies. The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead. The non-porous resin has particle size of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. On the top of the hydrophilic layer, weak cation-exchange functional groups are attached via a proprietary chemistry, resulting in high capacity ion-exchange layer.
