Improving Column Connections
A good connection is necessary for trouble-free chromatography.
Connecting incompatible fittings from different manufacturers
can result in leaks, poor peak shape, and increased void volume
(Figure 1). Each type of end-fitting has a unique seat depth or

fittings are interchangeable; whereas Waters, SSI, Rheodyne®,
and Gasukura fittings are not (Figure 2).
