Shim-pack XR Series columns use a 2.2 μm packing particle size and offer a skillful balance between resolution efficiency and pressure.
An XR Series column resolution equivalent to a general-purpose column with 5 μm packing particle size(Shimpack VP-ODS), but significantly
reduces the analysis time. The pressure on the column under many analysis conditions does not exceed 35 MPa. Consequently, ultrafast
analysis can be comfortably performed on an existing instrument
