Column Connectors

The column connectors are used to connect capillary columns with the same or different diameters.

Two different modifications are available:

• "Standard" column connectors are known for their solid mechanical assembly.
• "Light" column connectors are characterized by their minor wall thickness. This low-mass column connection technology enables a much quicker temperature adaption of the column connector to the GC oven temperature.

According to application, the following connectors are available:

• dual column connector: to connect two capillary columns
• triple column connector: to split the gas stream in two equal parts
• quadruple column connector: to split the gas stream into two equal parts and to supply an additional connection for purge gas or backflush
