Shim-pack HPLC Column Guidebook - High Performance Liquid Chromatography Columns

Význam tématu

High performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC) are cornerstone techniques in pharmaceuticals, environmental analysis, food safety and biochemistry. Columns with optimized stationary phases and particle sizes enable critical improvements in separation speed, resolution and sensitivity. Accurate column selection and performance are essential for reliable, efficient workflows in analytical laboratories.

Cíle a přehled studie / článku

This guide reviews the Shim-pack series of HPLC, UHPLC and SFC columns, ranging from analytical to preparative scales. It aims to summarize column families, performance characteristics and applications, and to illustrate method transfer strategies between high speed and conventional analyses.

Použitá metodika a instrumentace

Instrumentation include:

• Nexera X2 and Nexera XR UHPLC/HPLC systems
• Prominence HPLC and UFLC platforms
• Shimadzu LC-2010 series and LabTotal certified vials
• LCMS-8030 triple quadrupole mass spectrometer
• Ghost Trap DS/DS-HP mobile phase cleaners
• SFC modules and column switching valves (FCV-32AH/34AH/36AH)

Hlavní výsledky a diskuse

Key findings and discussion points include:

• Shim-pack XR series enables 2.2 μm columns with pressures up to 35 MPa for rapid analyses equivalent to 5 μm packings
• XR-ODS II and III columns tolerate 60–100 MPa, allowing high-resolution UHPLC with extended column lengths
• VP series deliver reproducible 5 μm columns optimized for method development and validation with consistent batch-to-batch performance
• Specialty phases (MAqC-ODS, GIST C18/AQ, GIS series) provide improved retention of polar, basic or acidic analytes without ion pairing reagents
• SFC columns (Shim-pack UC series) expand applications to supercritical mode, while preparative packings support scale-up
• Method transfer between high-speed and conventional analyses is streamlined by matching retention characteristics across column families
