HPLC Guard Columns and Cartridges
YMC America, Inc ProC18 RS guard 80A 5um 10x3mm
YMC-Pack Pro C18 RS exhibits elevated recognition of stereoselectivity due to high carbon trifunctional bonding Columns maintain a strong resistance to acid and alkali and the separation selectivity for compounds that differ only slightly in hydrophobicity is outstanding In addition extensive endcapping of the stationary phase results in excellent peak shape for basic compounds
YMC America, Inc PolyamII grd 120A 5um 10x3mm
YMC-Pack Polyamine II is a silica-based normal-phase stationary phase bonded with polyamine that is particularly useful for the separation of sugars The column lifetime in aqueous mobile phases is longer than conventional silica-based amino columns and is therefore applicable for the separation of oligosaccharides using high-aqueous mobile phases In addition YMC-Pack Polyamine II can be used to separate ionic compounds with a combination of normal-phase and weak anion-exchange modes
YMC America, Inc Ph guard 120A 3um 10x3mm
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
YMC America, Inc PVA-Sil guard 120A 5um 10x3mm
YMC-Pack PVA-Sil is prepared from a 5 m 120 silica support which is bonded with a monomolecular polymer coating of vinyl alcohol The polymerized PVA completely covers both external and internal surfaces of the silica support protecting it against aggressive high pH buffers and solvents
YMC America, Inc ProC4 guard 120A 3um 10x3mm
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 The wide pore butyl chemistry allows minimal distortion of tertiary conformation for large biomolecules and results in samples that are pure concentrated and high in biological activity
YMC America, Inc Cell-C guard 5um 20x4mm
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
YMC America, Inc Triart C8 grd 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 C4 guard 120A 20um 10x10mm
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
Mac-Mod Avantor ACE C18, 100 A, 5 um, 3.0/4.6 x 10 mm Guard Cartridges (5/pk)

Avantor ACE UHPLC alternatives columns are available under the ACE Excel brand.
YMC America, Inc SIL-HG guard 60A 10um 10x5mm
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
