Sepax Technologies Inc Sepax HPLC Column GP-C8, 5 µm, 120 Å, 30 x 50 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 Nanofilm SEC-250, 5 µm, 7.8 x 250 mm
Utilizing proprietary surface technologies, Nanofilm SEC phases are made of the uniform, hydrophilic, neutral, and polymeric thin films chemically bonded on the high purity and enhanced mechanical stability silica. Nanofilm SEC phases have been innovatively and specially designed to ensure high resolution and maximum recovery for the separation of biological molecules at low salt concentration or organic buffers. The narrow dispersed, spherical silica particles of the Nanofilm packings for SEC-150, SEC-250, and SEC-500 have nominal pore sizes at 150, 250, and 450 Å, respectively.
YMC America, Inc TriartC8 120A 5um 75x.3mm 1/32
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
Mac-Mod Vydac 218MS C18, 300 Å, 3 µm, 1.0 x 150 mm HPLC Column
Vydac TP was the first range of wide pore media phases developed and became the industry standard for peptide and protein separations. The 300 ¿TP silica gives polypeptide molecules complete access to the interior of the silica pores. Vydac TP is known for long column lifetime and negligible phase leaching. Vydac TP provides reliable protein purifications, scalable from analytical to preparative scale. Vydac 218TP and 238TP are used for small polypeptides of 4-5kDa, enzymatic digest fragments, natural and synthetic peptides and multi-ring compounds. Vydac 208TP is recommended for polypeptides of molecular weight 10-20kDa. Vydac 214TP is recommended for the analysis of glycoproteins, hemoglobin variants, histones, insulin variants and membrane proteins. Vydac 219TP is suitable for polypeptides with aromatic side chains, large hydrophobic proteins, membrane-spanning peptides, lipid peptides and fusion proteins from inclusion bodies.

YMC America, Inc Carotenoid 3um 50x.5mm 1/32
YMC Carotenoid is a C30 bonded silica-based reversed phase column that is markedly more hydrophobic than classical C18 phases Even when pure organic eluents are applied many sample solutes are retained The YMC Carotenoid C30 stationary phase provides sufficient phase thickness to enhance interaction with long chain molecules therefore geometric and positional isomers of conjugated double-bonding systems are recognized and resolved It can be used to separate carotenoids in blood samples food products natural product extracts and commercial preparations In addition YMC Carotenoid operates with low aqueous or non-aqueous mobile phases that are desirable in LC/MS and prep fraction recovery
Waters Corp Column, CORTECS C18, 90Å, 2.7 μm, 3 mm x 75 mm
CORTECS C18 Columns are general purpose, high-efficiency columns based on a solid-core particle that offer balanced retention of acids, bases & neutrals at low and mid-range pH. These columns allow for enhanced sample throughput and can be used to resolve complicated combinations or retain resolution while boosting throughput.
- Offers balanced retention of acids, bases & neutrals at low and mid-range pH.
- Solid-core particles decrease the three terms in the van Deemter equation (A, B, and C terms) for improved performance.
- Enables enhanced sample throughput and allows the use of shorter columns for comparable peak capacities and faster re-equilibration.
- Helps to run more samples in the same amount of time without sacrificing separation performance, saving lab operation costs.
- Certificates of analysis (COAs) are available online at www.waters.com/coa.
Waters Corp XSelect CSH C18 Method Validation Kit, 130Å, 5 µm, 4.6 mm X 100 mm, 3/pk
