YMC*Gel HG-series

High Grade Silica Phases for Preparative HPLC

YMC*Gel HG-series

    Particle Technology

    YMC has achieved considerable improvements in the manufacture of its classical silica base. This has given rise to an improved generation of stationary phases with superior physical attributes: YMC*Gel High Grade (HG)-series.

    Due to its improved mechanical stability and its more uniform pore and particle size distribution the benefits of YMC*Gel HG-series products are:

    • Higher sample load
    • Less backpressure
    • Longer column usage
    • More repacking times possible
    • More efficient column packing

    Available Phases are:

    • YMC*Gel Diol-HG
    • YMC*Gel SIL-HG (Silica)
    • YMC*Gel Ph-HG (Phenyl)
    • YMC*Gel NH2-HG (Amino)
    • YMC*Gel CN-HG (Cyano)
    • YMCbasic
    • YMC Omega

    The silica-based YMC*Gel Diol-HG is a rugged and efficient normal phase, reversed phase or size exclusion material. It is generally used for the separation of biomolecules and pharmaceuticals. As the non-specific adsorptive sites have been eliminated it exhibits better performance characteristics for size separations than nonbonded silica. YMC*Gel Diol-HG is available in four porosities: 6, 12, 20 and 30 nm. Diol- 12 is most suitable for the separation of peptides or oligosaccharides with molecular weights of 10,000 or less, whereas Diol-20, and -30 (either used individually or in combination) are suitable for separations of proteins and other water-soluble compounds with molecular weights of 10,000 to several hundred thousands.

    YMC*Gel SIL-HG is a fully scalable, high purity silica gel, which provides excellent batch-to-batch reproducibility and high sample recoveries. The totally porous spherical particles are mechanically and chemically stable, yet provide high surface area for greater sample loading and increased resolution.

    Improved Silica Base for Better Performance

    Improvements in the production process of the base silica has led to particles with higher mechanical stability and more uniform particle and pore size distribution (see microscopy images below).

     

     

    Tangible Improvements for your Process

    A narrower particle size distribution with lower tendency for the HG-silica material to produce fines translates directly into a reduced backpressure of preparative processes. On average a 7% backpressure reduction can be seen, which increases dramatically with each repacking step.

    Impact of Pore Size Differences

    YMC*Gel is available in a variety of different pore sizes. Pore sizes are usually matched to sample molecule sizes. Pore sizes can also be used to adjust ligand density and hence retention characteristics of a bonded phase, since the size of the pores also affects the total media surface area in a packed column.
