Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, SRT-C SEC-500, 5 µm, 4.6 x 50 mm, Light Scattering SEC
SRT-C SEC phase, developed based on innovative surface coating technology, comprises of uniform, hydrophilic, and neutral nanometer thick film chemically bonded to high purity and mechanically stabilized silica. SRT-C, uses lay-down monolayer on porous silica as oppose to SRT of stand-up monolayer, offers ideal phase chemistry for hydrophobic samples like insulin, membrane protein monoclonal antibodies derivatized with polymer branches (polypeptide or PEG) separation.

YMC America, Inc ODS-AHG guard 200A 10um 20x4mm
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 C4 guard 120A 10um 20x4mm
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 Diol-NP guard 60A 5um 10x10mm
YMC-Pack Diol-NP is a versatile alternative to silica for normal phase separations and provides much better reproducibility when compared to bare silica material It shows typical normal phase retention behavior when used with low-polarity mobile phases due to hydroxyl groups on the surface of the stationary phase acting as polar groups YMC-Pack Diol-NP can also be used in HILIC-mode with organic/water mobile phases
YMC America, Inc ODS-AQHG grd 120A 10um 10x4mm
YMC-Pack ODS-AQ is a unique reversed-phase material with both a hydrophobic high carbon loading and a relatively hydrophilic surface Because of the hydrophilic surface ODS-AQ can be wetted with polar eluents It provides chromatographers reproducible retention and excellent peak shape in highly aqueous mobile phases including 100% water This is due to the C18 ligands on ODS-AQ actually being lifted from the surface by the action of the eluents penetrating the silica pores Selectivity on YMC-Pack ODS-AQ can be subtly different from that seen on conventional ODS columns Differences in selectivity are most often encountered when analyzing mixtures of relatively polar compounds Typically longer retention and greater resolution are observed with ODS-AQ Available in both 120 and 200 pore sizes YMC-Pack ODS-AQ is well-suited for analysis and purification of peptides and other biomolecules
YMC America, Inc Cell-SZ guard 5um 10x20mm
YMC s CHIRAL ART series features polysaccharide-derived chiral stationary phases (CSPs) based on amylose and cellulose tris-carbamate derivatives available in both coated and immobilized formats These columns provide exceptional stereoselectivity durability and solvent versatility supporting normal-phase reversed-phase and supercritical fluid chromatography (SFC) modes
