YMC America, Inc ProC4 120A 5um 75x0.5mm 1/16
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 Tri C18 ExRS 80A 3um 33x4.6mm
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 HS C18 col 120A 3um 20x2mm
Hydrosphere C18 is based on highly inert ultra-pure pH neutral silica and is designed to maintain a hydrophilic surface for superior separation of hydrophilic compounds Minimal metal content and very low concentrations of residual silanols make this an ideal phase for the analysis of basic pharmaceuticals and chelating compounds even under LC-MS conditions such as separation in non-phosphate buffered systems In addition the ability to separate polar compounds under highly aqueous mobile phase conditions without loss in retention plate counts and peak performance greatly enhances the versatility of Hydrosphere C18
Waters Corporation Prep Column, Symmetry Shield RP8, 100Å, 5 μm, 19 mm X 100 mm
These reversed-phase columns feature patented embedded polar group technology to “shield” silica's residual silanol surface from basic analytes, reducing silanol activity. This improves peak shape, resolution, and prevents pore dewetting in aqueous mobile phases, ensuring analyte retention.
- Improved peak shape and resolution; reduced silanol activity.
- Prevents pore dewetting, ensures analyte retention, eliminates rewetting.
- Exceptional repeatability and consistent results.
- Less retention for basic compounds, aids method development.
- Excellent peak shape from high bonding density and low silanol activity.
- Optimizable at neutral or low pH; maintains peak shape.
- Accelerates novel methodology development and increases lab productivity.
- Long-lasting performance, lower equipment costs.

Microsolv Technology Corporation HPLC Column Set, PEEK, 2.1mm ID. Includes, 1 EA 30mm x 2.1mm Column Tube, Black, 2 EA 2um Frits, 2 EA End Fittings. 1 EA.
This complete column set is made with Victrex PEEK and we add graphite to achieve the black color of the 1/4" OD Column Tube, which is not treated with any chemicals. The polished interior is achieved through a very careful, proprietary, extrusion method.
YMC America, Inc Jsphr M80 80A 4um 75x.5mm 1/32
The J sphere series of columns consists of three kinds of ODS made from the same silica gel base each with a different ligand coverage The 4 um 80 silica support provides outstanding chromatographic efficiency while the high surface area material (500 m2/g) offers exceptional interaction with analytes This combination provides excellent peak symmetry across all J sphere products The variations in ligand coverage produce three columns with different hydrophobicity hydrogen bonding capacity and steric selectivity for tertiary structures Because of this J sphere can be used with confidence to identify structural differences of solutes and to improve the efficiency of separation optimization
