SecurityGuard ULTRA offers a convenient and economical way to extend core-shell, sub-2µm, and other UHPLC column lifetimes SecurityGuard™ ULTRA dramatically extends UHPLC column lifetime and is ideal for virtually any manufacturer's UHPLC, sub-2µm or core-shell columns. SecurityGuard ULTRA protects against the damaging effects of chemical contaminants and microparticulates introduced by the sample, mobile phase or system, whic…

Extends UHPLC, HPLC, SFC, and PREP column lifetime

PEG Versatility for Solvents, Acids, and AminesBonded, solvent rinsable phase excellent for separating polar complex mixturesGC/MS Certified low bleed levelsLow activity for aminesExcellent separations of polar complex mixtures; widely used for profiling and "fingerprinting"Recommended UseAlcohols, Aldehydes, Aromatics, Basic Compounds, Essential Oils, Flavors & Fragrances, Glycols, Pharmaceuticals, Solvents, Styrene, Xylene I…

SecurityGuard Guard Cartridge System Column Protection is designed to fit any manufacturers’ standard HPLC column, making it the ultimate HPLC Guard Column.   SecurityGuard Guard Cartridge System is guaranteed to extend the lifetime of your 2.0 mm, 3.0 mm, 3.2 mm, 4.6 mm, and 7.8mm ID column by capturing sample contaminants that can cause an increase in backpressure and effect baseline noise.     Features:…

Low Polarity for a Wide Range of SeparationsRugged, high efficiency, and MS Certified low bleedWell-suited for true boiling point separationsExcellent resolving power of critical pairs in complex petrochemical samplesUsed for “fingerprinting” and routine quality control analyses (e.g., citrus oils)Recommended ApplicationsAmines, Drugs, Essential Oils, Ethanol, Gases (Refinery), Hydrocarbons, Mercaptans, MTBE, Natural Gas Odora…

100% Aqueous Stability for Polar Compounds100% aqueous stable, excellent for aqueous samples; bonded and solvent rinseableExtremely inert for acidic compoundsEnhanced selectivity for low boiling solvents; high retention of alcohols and chlorinated solventsIncreased efficiency at 20 °CZB-WAXplus provides optimal selectivity for many aqueous soluble compounds such as those found in alcoholic beverages or glycol samples. The ZB-W…
