The SilTite μ-union from SGE Analytical Science simplifies connecting GC guard columns or columns for two-dimensional GC.
The device offers these advantages over other connectors and press-fits: it is chemically inert; has good operational stability and low dead volume; is easy to install; provides a leak-free connection.
The connector’s stainless steel surfaces are treated to ensure inertness and optimal chromatography. The device has low thermal mass and tracks the GC oven temperature during temperature programming so that chromatography is unaffected. The low dead volume of the GC connector ensures optimal peak shapes.
Installation is easy with FingerTite fittings that can be tightened with finger force, avoiding the need for tools or wrenches. The connector is claimed to achieve a perfect, reliable seal even for the most sensitive GCMS systems.
