Based on Core Enhanced Technology, using 4 µm solid core particles, these columns allow users of conventional HPLC methods to enjoy performance far beyond that of columns packed with 5, 4 or even 3 μm fully porous particles. Very high separation efficiencies, using standard HPLC instruments and conditions, provide increased peak resolution and lower limits of detection. An ultra-stable packed bed results in exceptionally robust columns that demonstrate excellent retention and response reproducibility.

These columns permit a simple, one stage clean-up as part of a methodology to determine pesticides in many organic matrices. The higher molecular weight fractions such as lipids, polymers, natural resins and dispersed high molecular weight components are easily eliminated in the GPC analysis.

Supplier: MICROSOLV

These carboxylic acid HPLC columns have a silica hydride surface similar to other TYPE-C™ Silica phases but the uniqueness of Cogent UDA™ is that they can exhibit weak cation exchange properties in addition to RP and ANP retention; a mixed mode is possible with some mobile phases conditions.

Supplier: Thermo Fisher Scientific

These reversed phase columns were developed in conjunction with the Vanquish™ UHPLC system to take advantage of the system's extended pressure capabilities and robustness. The result is a new level of separation, speed and throughput that solve analytical challenges of analysing complex matrices using liquid chromatography and LC-MS.

The ZORBAX® Bonus-RP column has a polar amide group embedded in a long alkyl chain. This novel bonding reduces interactions between basic compounds and the silica support, improving peak shape for the most difficult basic compounds. Peak shape and column lifetime are further improved by triple endcapping. In addition, diisopropyl side groups provide steric protection against acid hydrolysis for good lifetime and low pH. The Bonus-RP column provides an alternate selectivity to C18 and C8 alkyl bonded phases.

Supplier: Thermo Fisher Scientific

These columns result in a multimode separation mechanism including hydrophobic, anion-exchange and cation-exclusion interactions. Consequently, retention of basic, neutral and acidic molecules can be either independently or concurrently adjusted by changing ionic strength, pH and organic solvent content in the mobile phase.

Supplier: VARIAN

Microsorb™ C18 is an octadecylsilane-covered silica that has been bonded using monofunctional bonding agents under optimised conditions. This material is then endcapped with trimethylsilyl groups to minimise nonspecific binding, maximise mass recoveries and improve peak shape.

These columns offer a unique HILIC selectivity and low ion exchange activity. Based on Core Enhanced Technology, they provide fast, high resolution separations without the elevated back pressures required by sub-2 µm particles.

Supplier: Agilent

Poroshell 300 columns are ideal for fast separations of proteins and peptides because the superficially porous particle allows for fast flow rates to be used while maintaining sharp, efficient peaks. Peptides and proteins are typically separated slowly to reduce the potential peak broadening of these slow diffusing analytes. However, Poroshell columns use a superficially porous particle made with a thin layer of porous silica on a solid core of silica, reducing the diffusion distance for proteins making practical rapid HPLC separations of peptides and proteins up to 500 to 1000 kDa.
