Low-bleed GCMS column with excellent inertness for active compounds. General-purpose column - ideal for GC-MS analysis of semivolatiles, polycyclic aromatic compounds, chlorinated hydrocarbons, phthalates, phenols, amines, organochlorine pesticides, organophosphorus pesticides, drugs, solvent impurities, and hydrocarbons. Temperature range: -60C to 350C. For a 30m column with a 5m integrated guard, use 221-76161-30; for a 30m column with a 10m integrated guard, use 221-76162-30.
