Products/Services for gc column
Gas chromatography columns (GC columns) are of two types: packed and capillary. Solutes to be measured travel through the column at a rate primarily determined by their physical properties, and the temperature and composition of the column. Search by Specification | Learn More
High performance liquid chromatography (HPLC) columns use a liquid mobile phase to separate the components of a mixture. Search by Specification | Learn More
Gas chromatography detectors (GC detectors) identify solutes as they exit the chromatographic column. A chromatogram is generated plotting the signal versus time. Search by Specification | Learn More
...are dissolved in a solvent and forced to flow through a chromatographic column under high pressure. Medium pressure liquid chromatography is used with substances that cannot be resolved chromatographically at atmospheric pressures. Gas chromatographs (GC... Learn More
Tooling plates and tooling columns provide mounting or clamping surfaces for holding and positioning vises, clamps and workpieces during setup, manufacturing and dimensional inspection. Learn More
Columns are vertical structural elements that use compression to transmit the weight of a structure above to other structural elements below. Learn More
...a separation column with a stationary phase, and a detector. Differences in partitioning behavior between the mobile phase and the stationary phase cause the separation of compounds. Gas chromatographs use many different detection methods. Choices include... Search by Specification | Learn More
...rather than enter the solid as in absorption. An aeration column is used when treating wastewater and involves pumping the water through a series of columns to add oxygen to the wastewater. Aeration increases the surface area of the contaminated water... Learn More
High performance liquid chromatographs (HPLC) use a liquid mobile phase to separate the components of a mixture. The components are dissolved in a solvent and forced to flow through a chromatographic column under high pressure. Search by Specification | Learn More
Chromatography membranes are designed for separation tasks in laboratory and industrial applications. They are built-in membrane systems such as plate and frame, spiral-wound module, hollow fibre module, and tube-in-shell module. Learn More
High performance liquid chromatograph (HPLC) detectors pass a beam of light through a column effluent as the fluid passes through a low-volume flow cell. Variations in light intensity are recorded and a chromatograph is generated. Search by Specification | Learn More
Mass spectrometers separate ions by their mass-to-charge (m/z) ratios. They are used to identify compounds by the mass of one or more elements in the compound. They are also used to determine the isotopic composition of one or more elements in a compound. Search by Specification | Learn More
...for steam condensation without restricting air flow. Tower packing is a mass of inert, solid shapes. Within a cylindrical column, it provides a greater surface area for the gas and liquid in a web scrubber to make contact. Applications for tower... Learn More
...as laboratory standards, as well as for detection, sample preparation, environmental monitoring, and analysis applications. Analytical or laboratory applications may include gas chromatography (GC, GC-MS, LC-MS), spectrometry (ICP, ICP-MS, Flame... Learn More
Air scrubbers, wet scrubbers, and gas scrubbers are air pollution control devices that use a high-energy liquid spray to remove aerosol and gaseous pollutants from an air stream. The gases are removed either by absorption or chemical reaction. Search by Specification | Learn More

Product News for gc column
EZ-Guard™ GC Columns
Guard columns (retention gaps) are often added to the front of the analytical column for protecting for contamination or to act as band focusing device when introducing a liquid sample into the capillary (with on-column and splitless injection techniques). The Varian EZ-Guard column is combination of a FactorFour column with a built-in Varian made guard column. (read more)
