Manufacturer & Supplier of Gas Generators for GC

1. Manufacturer & Supplier of Gas Generators for GC For over 30 years, the QUADREX CORPORATION has invested a wealth of scientific expertise into the manufacturing of its line of GC capillary columns. Quadrex, in a joint effort with the Zoex Corporation (Lincoln, NE) developed the first device to simplify capillary column installation. The Capillary Column Quick-Connect was introduced at the 1992 Pittsburgh Conference. The Quick-Connect fitting eased the column installation burden, also saving time and materials. Our close work with Zoex also pioneered early GC x GC instrumentation and column development. Quadrex has established strategic partnerships with other manufacturers for the supply of related products, such as Ultra-ALLOYTM Stainless Steel Columns from Frontier Labs (Japan), full-featured portable GCs from SRI Instruments, gas generator systems from Peak Scientific (U.K.) , and a complete line of GC consumables. With these relationships, we can offer you, the discerning chromatographer, complete GC systems, from consumables to GC instrumentation. Capillary Columns: Quadrex fused silica columns are produced with the industry standard polyimide outer coating (390°C maximum temperature) for most general GC applications. Columns with high temperature polyimide coatings, for applications >400°C, are available upon request. Each stationary phase used in our coating processes is synthesized and cleaned in-house to insure column to column reproducibility. All Quadrex phases are bonded to the silica substrate and cross-linked. Our stringent QA / QC program governs the production of all in-house phases which results in accurate selectivity, reproducibility, and outstanding thermal stability. GC Consumables: Quadrex offers a complete line of GC consumables that most often requiring routine replacement. Some products that are available with us are:     Graphite and Graphite/tl-polyimide™ Ferrules* Injector Port Liners Septa Carrier Gas Traps and Filters Sri Full Featured Portable GCs: SRI Instruments manufactures pre-configured and custom full-featured portable GCs offering a wide range of analytical solutions on flexible and inexpensive GC mainframes. All standard injectors and detectors are available, including accessories such as gas-sampling valves, purge and trap, headspace, vacuum pump interface, and methanizer. Each SRI GC includes Peaksimple Data Acquisition software to make your GC purchase complete. Peaksimple systems are also available as 1- and 6-channel stand-alone acquisition systems for ANY brand of GC. Hydrogen, Nitrogen, and Zero-Air Gas Generators: Peak Scientific laboratory Gas Generators can provide you with a total solution to your gas requirements. Peak Gas Generators can supply Nitrogen,

2. Hydrogen, and Zero Air gas, available with different flow rates, purities and pressures to suit your application.
