Waters Corp VanGuard Pre-column, C18, 100Å, 1.8 μm, 2.1 mm
The ACQUITY UPLC Peptide HSS T3 VanGuard Pre-column is designed to protect and extend the lifetime of analytical columns without compromising chromatographic performance. It uses HSS T3 particles, suitable for separations requiring silica-based selectivities or increased retention of hydrophilic peptides. This pre-column helps filter out chemical or particle contaminants from the mobile phase stream, thereby increasing the analytical performance of the column.
- Protects and prolongs analytical column lifetimes.
- Maintains chromatographic performance.
- HSS T3 particles provide silica-based selectivities and increased retention of hydrophilic peptides.
- Filters chemical or particle contaminants from the mobile phase.
- Manufactured to cGMP and ISO 9001 guidelines.
- Extends UPLC analytical column life across UPLC, UHPLC, and HPLC systems.
- Tested and approved for intended usage.
YMC America, Inc TMS guard 120A 5um 10x4mm
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 C4 guard 120A 5um 10x4mm
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 CN-HG guard 120A 20um 50x20mm
YMC-Pack CN can be used for both normal phase and reversed phase analyses due to the medium polarity of the cyanopropyl phase bonded to the silica base particle It can be used in normal phase with low-polarity mobile phases such as hexane or in reversed phase with highly-polar mobile phases such as methanol and water YMC-Pack CN can be useful for shortening analysis time in situations where retention is substantial using C18 or C8 or when separation optimization is difficult
YMC America, Inc PVA-Sil grd 120A 5um 10x30mm
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 NH2 guard 120A 5um 10x10mm
YMC-Pack NH2 is a normal phase separation column utilizing the polarity of primary amino groups bonded to silica It is a versatile stationary phase often used for the separation of sugars but can also be used for separations utilizing weak anion-exchange
YMC America, Inc Cell-SC guard 5um 20x3mm
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
