Quadrex offers a full range of bonded phases, all standard I.D.'s and the widest range of film thickness available from any column manufacturer. Also available are specially columns for environmental, petrochemical, high temperature and triglycrides analysis, and columns for high speed analyses.

VICI Valco Instruments offers ValcoBond® capillary columns, to meet the highest quality standards for resolution, retention characteristics, inertness, bleed, and reporducibility. ValcoBond uses proprietary liquid phase processing to produce low bleed characteristics while maintaining identical retention characteristics to the phases you are used to. These processes combine with proprietary automated deactivation, coating, curing bonding, and crosslinking to produce MS-certified bleed characteristics.
