Thomas Scientific offers a large selection of ferrules made from PTFE, Graphite, Vespel® and Vespel/Graphite composites. Ferrule sizes refer to the size of the fittings into which they fit; they are not the diameter of the ferrule. (For example, 1/16" ferrules are 1/8" diameter.) …

Similar to CG-1186 but with a sealed in COARSE porosity fritted disc to support column packing. Lower end of the column has a round bottom. Column is constructed using MEDIUM WALL TUBING.

3x faster multiresidue pesticides analysis in foods. Factory-coupled, leak-free kit makes setting up LPGC as simple as a column change. Ideal for speeding up GC-MS and GC-MS/MS methods. Integrated transfer line reduces background and stabilization time.

Capillary ferrules are packaged in dial packs which deliver one ferrule at a time, keeping the others clean and ready for use. The dial packaging has been tested to ensure no out gassing of contaminants, including phthalates. *These ferrules are recommended for use with Agilent GC/MS…

HP-INNOWax is a polyethylene glycol (PEG) stationary phase that features high polarity and high upper temperature limits. It is a close equivalent to USP phase G16 and is targeted at food, flavor, and fragrance applications. The improved line of Agilent J&W HP-INNOWax GC columns utilizes…

Accurate quantification of toluene and benzene—including benzene in gasoline containing ethanol or butanol blends. Complete resolution of benzene from ethanol—no compromising coelutions. Enhanced formulation with improved support material and polymers—more robust and reproducible. Column sets…

Temperature range -20°C to 240°C Equivalent to USP G43 phase

Chemists using guard columns in the analyses of basic compounds frequently observe peak tailing and low recovery. This happens because conventionally deactivated tubing surfaces can be adsorptive to basic compounds. Restek offers base-deactivated guard columns, as well as base-deactivated inlet…

HYDRODEX cyclodextrin phases Capillary columns for GC enantiomer separation Features Base material: cyclic oligosaccharides consisting of seven (β-cyclodextrin) or eight (γ-cyclodextrin) glucose units bonded through α-1,4-linkages Regioselective derivatization…

In the past it was necessary to use Press-fit connectors with specific dimensions to connect columns of those dimensions. Modern Press-fit connectors are “laser-milled” to provide highly reproducible taper angles throughout the length of the Press-fit insuring an excellent seal. Now the…

Equivalent to USP G1, G2 and G38 phases Temperature range -60°C to 350/400°C

low-polarity phase; Crossbond 1,4-bis(dimethylsiloxy)phenylene dimethyl polysiloxane Rxi fused silica capillary GC columns were designed specifically to be the best columns available, for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. In addition to…

Recommended application: Preparation of capillary columns As precolumns, whenever a larger contamination capacity is required Different deactivations are available: Methyl-Sil deactivated Phenyl-Sil deactivated CW deactivated

30% heptakis (2,3-di-O-methyl-6-O-t-butyl dimethylsilyl)-β -cyclodextrin in DB-1701 Chiral separations without chiral specific derivatization New stationary phase for improved resolution of many chiral separations Suitable for many chiral γ -lactones and terpenes Similar…

Application: The 5% phenyl equivalent phase provides a boiling point elution order with a slight increase in selectivity, especially for aromatic compounds. The low bleed characteristics, inertness, and durable nature make it the column of choice for environmental analytes (such as semivolatiles,…

COL-4032 FULL RANGE H2

Temperature range -40°C to 240/260°C.

In packed columns, the carrier gas percolates through the porous bed. In a packed column, separation is achieved by moving the solutes apart. Packed columns are made up of two main materials; stainless steel and Pyrex glass. Metal packed columns are more suitable for long and high carrier gas flow…

Temperature range -60°C to 300/315°C.

GC capillary columns are typically wound on 7 inch cages that fit into standard-sized GCs like the 6890. The 6850 GC has a smaller oven which requires the use of columns wound on a smaller cage diameter. Polyethylene glycol (PEG) Close equivalent to USP Phase G16 High polarity …
