Silica ( Silicon dioxide, silica gel, SiO2) is one of the most abundant minerals on earth, accounting for 59% of the mass of the Earth’s crust. It is also one of the most common materials used in chromatographic separation. But don’t let its abundance – its commonness – fool you. See more The shape of silica particles can have a significant impact on separation efficiency. Spherical particle shapes result in more homogenous packing characteristics than irregular shapes. Spherical silicas are more resolutive, and … See more Matching particle size to the targeted application is essential, with different particle sizes used for different analytes. While the most … See more As with particle size, pore size selection is highly dependent on both the target analyte and the type of chromatography being performed. Bigger pore sizes (larger pore diameters) tend to lead to lower surface availability, … See more Silica gel particle size, discussed above, has an obvious impact on performance – and so does particle size distribution (PSD). PSD indicates the proportion of different particle … See more WebStandardized silica gels from Merck are produced using a traditional method in the world’s largest and most modern production plant for chromatography grade silica gels. … the packhorse inn mapledurham
