to the air sampling pipe.

Note: It is important that the air sampling pipe is branched in the direction away from the detector.
3.5 Reducing Connectors
Reducing connectors are used to attach pipes having different internal/outer diameters. These are typically
used to connect capillary tubes and drop pipes to the sampling pipe.
