<strong>UltraShield</strong> <strong>Pre</strong>-<strong>column</strong> <strong>Filters</strong>• Low cost protection against <strong>column</strong> failure dueto micro-particles• Suitable for use at 15,000 psi• Low volume, maintains <strong>column</strong> performance• All stainless steel flow path• Universal fitProtecting UHPLC <strong>column</strong>s (< 3 μm particle size)from damage due to particulate matter in thesample and mobile phase is extremely important.Many of these <strong>column</strong>s are produced with 0.2 μminlet frits, making them highly vulnerable toplugging. Creating an economical pre-<strong>column</strong> filterthat can adequately protect a UHPLC <strong>column</strong> whilemaintaining <strong>column</strong> efficiency is no easy task.<strong>UltraShield</strong> was engineered specifically for use infast, high efficiency separations requiring highmobile phase velocities and ultra-high pressure.<strong>UltraShield</strong> maintains the efficiency of these highperformance <strong>column</strong>s, assuring no loss of criticalresolution.With its simple design, <strong>UltraShield</strong> installs in anyanalytical <strong>column</strong> in seconds and is leak tight to15,000 psi. Simply finger tighten initially, then wrenchtighten an additional ¼ turn. The <strong>UltraShield</strong>design is universal and can be installed in any brandof UHPLC <strong>column</strong>.<strong>UltraShield</strong> <strong>Pre</strong>-Column <strong>Filters</strong> Maintain Critical ResolutionAbsorbance 254 nm (mAU)Absorbance 254 nm (mAU)Injection without <strong>UltraShield</strong>1Injection with <strong>UltraShield</strong>1As the above chromatograms illustrate, <strong>UltraShield</strong> pre-<strong>column</strong>filters maintain the theoretical plates, N, of very efficient UHPLC<strong>column</strong>s.
