Low Polarity for a Wide Range of Applications; Rugged, high efficiency, and MS Certified low bleed. Well-suited for true boiling point separations. Excellent resolving power of critical pairs in complex petrochemical samples. Used for “fingerprinting” and routine quality control analyses (e.g., citrus oils).
Alternate Selectivity for Mid-Polarity Analyses; Fast run and re-equilibration times for enhanced sample throughput and productivity. Provides alternate selectivity to phenyl phases with similar polarity.
Popular choice for residual solvent testing (USP Monograph). Widely used to separate volatile organic flavor and fragrance additives and residual solvents in industrial or pharmaceutical products (OVIs). Increased temperature limit speeds run times and re-equilibration. Formulated for low bleed.
Enhanced Aqueous Stability: 100 % aqueous stable, excellent for aqueous samples; bonded and solvent rinsable. Extremely inert for actidic compoundss. Enhanced selectivity for low boiling solvents. High retention of alcohols and chlorinated solvents. Increased efficiency at 20 °C.
Unique low polarity si-arylene column for MS detectors. Provides alternative selectivity to standard 5-type phases. Often used for confirmation of pesticide, PCB, or other environmental sample. Good tool for sample screening to identify unknown contaminants.
Specially designed for the separation of all types of pesticides, herbicides, and insecticides. Well-suited for dual column analysis with Zebron ZB-MultiResidue™-2. Performance exceeds US EPA Method 8081A specifications for chlorinated pesticides. Low activity, decreased breakdown of sensitive pesticides such as DDT. MS Certified phases ...
Performance that exceeds US EPA Method 8081A specifications. Low activity, decreased breakdown of sensitive pesticides such as DDT. MS Certified phases provide low bleed performance for pesticide confirmation by MS.
Low Bleed, Intermediate Polarity Selectivity for GC/MS; Intermediate polarity column for high molecular weight analysis. Inert to minimize analyte adsorption, improve efficiency, and reproducibility. More rugged (longer column life) than other polar phases. Excellent for trace analysis with bleed-sensitive detectors (MS, FID, ECD, NPD).
High polarity column with excellent thermal and chemical stability. Provides better peak shape for underivatized acids. Especially suited for organic acids, free fatty acids, and alcohols. Bonded, solvent rinsable FFAP phase. Replaces OV-351.
Rugged Performance for High Polarity Selectivity; High polarity column capable of high temperature bakeout to remove contaminants. Inert to minimize analyte adsorption, improve efficiency, and reproducibility. More rugged (longer column life) than other polar phases. Great for toxicology and environmental compounds.
Low Bleed Performance for GC/MS: Very low bleed (MS Certified) especially suited to high sensitivity GC/MS. Improved signal-to-noise ratio for better sensitivity and mass spectral integrity. Extremely inert for active compounds such as drugs, pesticides, acids, and bases.
Bonded, solvent rinsable phase excellent for separating polar complex mixtures. MS certified, low bleed levels. Low activity for amines. Excellent chromatography of polar complex mixtures; widely used for profiling and 'fingerprinting'.
Low Bleed Performance for GC/MS; Most popular starting column for method developers. Arylene Matrix Technology (AMT) provides a highly stable arylene phase for enhanced resolution of PAHs and multi-ring aromatic compounds. Low bleed (MS certified) especially suited to high sensitivity work using GC/MS.
Highly inert for improved peak shape of acidic/basic compounds, drugs of abuse, and pesticides. MS certified low bleed levels provide maximum sensitivity. Industry leading QC specifications ensure column-to-column performance. Traditional bonding chemistry provides the same selectivity as the ZB-5 columns.
