Strict Manufacturing Uniformity 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.

Balance of Column Efficiency and Column Backpressure Shim-pack VP series achieves a higher column efficiency while maintaining low pressure. It provides superior performance shown by NTP (Number of Theoretical Plates) per 1MPa.
Column Size: 4.6 x 150 mm, Mobile Phase: Methanol/Water=70/30, Flow Rate: 1.0 mL/min., Sample: Naphthalene
