More Information
Summary:A new type of tubular assembly especially adaptable to capillary columns for use in gas chromatography, comprises a capillary wound on and fused to a hollow mandrel and stress relieved by heating. The entire assembly is rigid and is more resistant to fractures than prior available columns. Variants include rigid assemblies integral with heating means. Solid, brittle stationary phases can be readily accommodated in these assemblies because of their rigidity and structural strength.
