YMC-Pack Silica

The high purity YMC-Gel Silica allows almost total sample recovery because the low content of impurities such as residual metals reduces non-specific sample adsorption. This also prevents unusual peak-shapes thereby encouraging higher sample loading. In addition, the porous structure of the spheres gives a high surface area which further improves sample loading.
Compared with irregular silica, YMC’s spherical material is subject to a much lower degree of mechanical degradation during packing and usage. This results in lower backpressures and extended column life times due to the absence of ‘fines’.
Since YMC spherical silica is the basis for every YMC bonded phase, this is a further reason for the premium quality of YMC stationary phases as far as backpressure and chromatographic stability is concerned.

Features:

• ultra high purity silica
• high mechanical stability
• highly porous, totally spherical particles
• available for analytical, semi-prep, preparative and process scale applications
• convenient for separation of compounds with similar structures
•  

Due to the highly sophisticated production process YMC’s highly spherical silica material shows premium performance and great lot-to-lot reproducibility. The reason for this can be summarised in two main qualities: very narrow physical and chemical product specifications and outstanding purity.
