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. Their stringent QA / QC program governs the production of all in-house phases which results in accurate selectivity, reproducibility, and outstanding thermal stability.
