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.
