Open and packed gas chromatography columns; includes retention gap columns for focusing liquid samples and guard columns to protect the analytical column from contamination.
Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.
Give greater stability and inertness at elevated temperatures and when working with highly active compounds with Thermo Scientific™ TraceGOLD™ TG-5MT Metal GC Columns.
