HPLC Guard Columns and Cartridges
YMC America, Inc Triart C8 grd 120A 3um 10x3mm
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 TMS guard 120A 3um 10x3mm
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 PVA-Sil guard 120A 5um 20x3mm
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 C4-HG guard 300A 15um 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 Amyl-SA guard 10um 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 YMCbasic guard 10um 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 ODS-AQ 3UM 200A 20X2.1MM PK/5
AQ20S03-02Q1GC: ODS-AQ, 3um, 200A, 20X2.1mm Cartridge, pk/5
Mac-Mod Avantor Prevail Silica, 110 Å, 5 µm, 3.0 x 7.5 mm Guard Cartridges (3/pk)
Avantor Prevail HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. Avantor Prevail HPLC columns are silica based except for Prevail Carbohydrate ES. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes. Avantor Prevail HPLC columns are stable from highly organic to highly aqueous. Avantor Prevail HPLC columns are specialty phases for specific applications. Avantor Prevail HPLC columns provide excellent sensitivity with microbore and ELSD applications.
