Shim-pack™ VP Series
Shim-pack VP series ensures high column-to-column performance reproducibility, which is ideal for method development and validation. Silica-bases, surface treatment and packing procedures are subjected to a strict array of quality criteria tests and controlled respectively. Each column is delivered together with Certificate of Compliance and Column Performance Report.
Features
Strict Manufacturing Uniformity
Comparison of reproducibility between three batches of silica-based materials
Balance of Number of Theoretical Plates and Column Pressure
Shim-pack VP series achieves a higher number of theoretical plates while maintaining low pressure. It provides superior performance shown by NTP per 1MPa.
Excellent Peak Shape
Packing materials with less metal impurities achieve excellent peak shape of coordination compounds.
Smooth Transfer of Methods from High-Speed Analysis to Conventional Analysis
By using the Shim-pack VP series of conventional columns in combination with the Shim-pack XR series of high-speed columns, which offer the equivalent separation performance, it is possible to perform method development via high-speed analysis...
Shim-pack™ XR Series
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 (Shim-pack 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.
Features
Shim-pack XR Series Columns Offer Versatility and Fast Analysis
Shim-pack XR-ODS Permits Simple Switching from Conventional Analysis
The two chromatograms to the right show conventional analysis that is performed faster. The lower chromatogram is the result of analysis using a Shimadzu Shim-pack VP-ODS general-purpose column.
Shim-pack XR Series Comprehensive Product Range
Customers can select the ideal column for the intended analysis. In addition to the versatile Shim-pack XR-ODS that is bonded with the C18 group, the comprehensive Shim-pack XR Series product range includes the Shim-pack XR-C8 that is bonded with the C8 group to give different retention behavior to ODS...
Shim-pack XR-ODSII/III High-Pressure Columns for Higher Resolution and Sensitivity
While the Shim-pack XR-ODSII/III use the same 2.2 μm packing particle size as the Shim-pack XR Series columns, they have higher 60/100 MPa pressure tolerance to achieve high-resolution fast analysis in a long column using a water/methanol mobile phase.
