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.
