Agilent J&W DB-MTBE columns feature a low-polarity stationary phase that resolves MTBE from 2-methylpentane and 3-methylpentane. Extensively tested to the strictest industry QC standards, these columns are bonded, crosslinked, and solvent rinsable, and are precision engineered for purge-and-trap injection without cryofocusing. DB-MTBE columns operate effectively within temperature limits of 35 to 260/280 °C.
