Oxygen leaks? Poor peak shape? Reduce GC column degradation and breakdown of active compounds such as acids, bases, and pesticides with Phenomenex® Easy Seals™. Designed with a softer metal alloy than traditional inlet base seals, Easy Seals make proper GC inlet base seal installation easier by reducing the torque ...
The Cool-Lock Nut is a unique device (patent pending) that simplifies GC column installation and eliminates the need for wrenches or other tools. The low thermal mass design allows the Cool-Lock Nut to cool rapidly, preventing users from burning their fingers during column changes. Other unique design elements prevent the column from slipping to ...

The Series 100 Thermal Conductivity Detector GC uses four sensing elements that are connected to form an electrical Wheatstone bridge circuit. These elements are miniature rhenium-tungsten filaments, which are mounted in a metallic cell block. A flow through type thermal conductivity cell is normally used in this analyser. A diffusion type ...
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).
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.
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.
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.
New Glass Infusion technology provides higher efficiency and greater column-to-column reproducibility. Increased accuracy for high temperature simulated distillation analysis. Up to 70 % more efficiency than other columns. Improved resolution of C50/C52.
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 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).
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.
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.
