UHPLC Applications

  • Engineered specifically for use in fast, high efficiency UHPLC separations requiring high mobile phase velocities and ultra-high pressures
  • The ultra-low dispersion of UltraShield maintains the efficiency of UHPLC columns, assuring no loss of critical resolution
  • With its simple design, UltraShield installs on any analytical, UHPLC or UPLC® column in seconds and is leak tight to 1000 bar (15,000 psi). Simply finger tighten initially, then wrench tighten beyond finger tight an additional ¼ turn
  • Available in 3 unique formats Ultrashield, Ultrashield WW and Ultrashield WP

Differences in the 3 Ultrashield versions

UltraShield WP Waters®, Agilent, Shimadzu, Thermo, Dionex, Hitrachi, etc Waters® Columns on UHPLC and Waters® UPLC® Instrumentation

HPLC Applications

ColumnShield Pre-column filters are designed to provide similar protection as UltraShield Pre- column filters but are for hand-tight applications for HPLC applications

  • Designed for sub-5 micron particles with sub-3.0 mm ID and shorter column lengths that generate narrow peak volumes
  • They provide effective, low-dispersion filtering at a lower cost than the UltraShield.
  • Although they are not recommended for ultra-high pressure applications, they can still be safely used at pressures up to 400 bar (6,000 psi)
  • ColumnShield pre-column filters utilize a PEEK finger-tight design that connects directly to any 1/16” 10-32 internal thread inlet fitting port, regardless of the manufacturer.

Column Saver Pre-column filters

  • Column Savers provide economical protection for HPLC columns packed with 3 µm particle size or larger and with bore sizes (internal diameter) 3.0mm to 8.0mm.
  • Use these Pre-column filters on the inlet of guard columns to extend the life and reduce the replacement costs of these items.
