The TraceGold gas-chromatography (GC) column is equipped with SafeGuard, a system which combines an analytical GC column with a built-in guard column. GC columns are routinely cut to remove contaminant deposits, but over time, the practice compromises peak resolution and separation accuracy. With the TraceGold GC Column with SafeGuard, users can cut columns for during routine maintenance with no impact on the chromatography performance of the column. SafeGuard is available in a variety of guard column lengths and column specifications. The system is suitable for applications with involatile sample matrices, including petrochemical, environmental and food analyses. — ThermoFisher Scientific, Atlanta, Ga.
