Columns Products (8117)

Similar to CG-1192 but with a sealed in COARSE porosity fritted disc to support column packing. Column is constructed using MEDIUM WALL TUBING. Can be used as a gravity eluted column or a flash column (as described by W.C. Still, M. Kahn and A. Mitra of Columbia University in JOURNAL OF ORGANIC...

Ideal for use with gel filtration, ion exchange, affinity and adsorption media Economical Easy to use Universal fittings and tubing connections Ideal for use with gel filtration, ion exchange, affinity and adsorption media. Polypropylene reservoirs and column outlets are permanently connected to a...

High efficiency separations at any pH The Hamilton PRP-C18 is a new HPLC column designed to provide high-efficiency, reversed-phase separations over an extended column life in nearly any mobile phase or pH. The rigid stationary phase has excellent mechanical and thermal stability (> 100°C),...

Polymeric 100 Å columns for general reversed phase separations. pH stable from 1 to 13 Better sample recovery than silica-based columns (there are no silanol groups) Excellent durability (stable to any concentration of water or organic solvent)   Five particle sizes: 5, 7, 10, 12-20 and...

5% Phenyl Polysilphenylene-Siloxane High temperature General Purpose GC column - suitable for over 80% of all routine analyses performed by gas chromatography Very Low Bleed - ideal for trace analysis Non-Polar Extremely inert Ideal for GC-MS Application Areas: Ultra trace analyses,...

Agilent ZORBAX Eclipse XDB columns – C18, C8, Phenyl and CN – provide four bonded phase choices for method development optimization. These columns provide good peak shape over a wide pH range (2-9) for additional method development flexibility with one family of columns. Eclipse XDB...

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. DB-5 (2713R99, T86, T94 and V89) (5%-Phenyl)-methylpolysiloxane Non-polar Excellent general...

MINI UV LAMP, 4W, WHITE/UV, 4AA

General purpose gravity eluted column having a PTFE stopcock and reinforced beaded top. Column is constructed using MEDIUM WALL TUBING. Glass wool (not supplied) is used to support column packing. Lower end of the column has a round bottom.

Simple absorption chromatography column for rapid preparative separations with moderate resolution. Allows separations of samples from 0.01 to 10.0g3 in 10-15 minutes. Column and reservoir, only, are Epoxy Coated. Reservoir connects between column and flow control adap-ter. Joints on column,...

midpolarity Crossbond phase 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 outstanding performance, this combination of column characteristics...

nonpolar phase; Crossbond dimethyl polysiloxane MXT-1 columns exhibit long lifetime and very low bleed at high operating temperatures. A proprietary synthesis process eliminates residual catalysts that could cause degradation and increase bleed. General-purpose columns for solvent impurities, PCB...

The use of SPE sample preparation can significantly enhance the robustness and reliability of many biological, pharmaceutical, forensic and environmental applications. Thermo Scientific™ HyperSep C18 SPE Cartridges feature a highly retentive alkyl-bonded phase for nonpolar to moderately polar...

nonpolar phase; Crossbond dimethyl polysiloxane General-purpose columns for solvent impurities, PCB congeners (e.g., Aroclor mixes), simulated distillation, arson accelerants, gases, natural gas odorants, sulfur compounds, essential oils, hydrocarbons, semivolatiles, pesticides, oxygenates. Long...

low-polarity phase; Crossbond diphenyl 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 outstanding performance, this...
