This allows for better separation than the typical particle size of 5um that are used in HPLC. Silica, C18, C8, NH2, CN, phenyl columns are available. Pressure limits are > 400 bar (600 - 1200 bar is typical) Everything else about column selection remains the same! It differs from conventional LC in two important respects: average particle size for UPLC is 1.7 μm versus 5.0 μm for ordinary columns, and the system runs at 15,000 psi rather than the usual 5000. All the well known advantages of ACE HPLC columns are now available for UHPLC.. The operating principle of HPLC and UPLC are the same. Hplc column volume calculator. Kinitex C-18 UPLC column (50 × 2.1 mm i.d., 2.6 μm particle size) gave better resolution but the count of theoretical plate was <2000. In general, UHPLC has the ability to separate sample constituents in a shorter timeframe—we consider it to be higher efficiency chromatography, owing to the use of smaller particle LC columns (1.7 to 3 µm). The general-purpose Restek C18 is a conventional monomeric octadecylsilane column suitable for analyses of a wide range of compounds from acidic through slightly basic. Quick links. Back pressure will increase with decrease in particle size; Efficiency will increase with decrease in particle size; With scale up change in hardware and flow cell may be required . Based on BEH technology the ACQUITY Amide columns offer a chemically stable, trifunctionally bonded amide phase that is stable from . Description of C4 HPLC Columns. This leads to shortening of analysis time and great savings in solvent consumption. Since back pressure is proportional to flow rate, the smaller particle size causes extreme operating pressures, resulting in a system that is well designed for resistance to high pressures. Thus, HPLC systems can handle pressures up to 6000 psi, whereas UPLC systems can handle pressures up to 15,000 psi. More advanced calculations can be found on the system suitability and pressure-flow pages. Furthermore the column inner diameter is varying. Miniaturization embracing instrumentation, column particle size, and column dimensions is one of the major current trends in separation techniques.
