Webchromatography, technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase. The mobile phase may be either a liquid or a gas, while the stationary phase is either a solid or a liquid.

WebApr 26, 2024 · M.S.GEL silica EP-DF grades are designed for both analytical and preparative UPHLC with particle sizes from 1.5 to 5 µm. Surface areas measure 30 ~ 800 m2/g and pore size diameter from 60 ~ … 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 how to mitre quilt borders

WebObjective: To establish an ion chromatography (IC) method for determination of ammonia in air of workplace. Methods: Ammonia in workplace air was collected in silica gel tube, desorbed with 10 mmol/L methanesulfonic acid by ultrasonic for 10 min, determined by IC. Results: The linearity range was 0.02-1.00 microg/ml. The linear equation was Y = … WebClassical silica TLC plates are available with glass, aluminium or plastic backings in a wide range of sizes, from 20 x 20 cm to 2.5 x 7.5 cm.
