Shim-pack VP Series - Features
HPLC Column
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.
NTP per 1MPa
Column Size: 4.6 x 150 mm, Mobile Phase: Methanol/Water=70/30,
Flow Rate: 1.0 mL/min., Sample: Naphthalene
Excellent Peak Shape
Packing materials with less metal impurities achieve excellent peak shape of coordination compounds.
Completed end-capping achieves excellent peak shape of basic 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, and then smoothly transfer to conventional analysis. Utilizing these columns with Nexera Method Scouting provides strong support for method development.
