High separation analysis --- 3 times better separation
Although the Shim-pack XR-ODS has a smaller diameter particle packing material, pressure loss (back pressure) is minimized, and a longer column can be easily employed as a fast LC column. Therefore, without making analysis time longer, it is possible to obtain a high-separation chromatogram with a high theoretical plate number, which could not be achieved previously. The following chromatograms compare Benzo fluoranthene isomer separation using Prominence UFLC with a Shim-pack XR-ODS and conventional LC. Prominence UFLC offers a shorter analysis time and significantly better resolution (Rs), and three times higher theoretical plate number.
