ImprovingColumnConnections
A good connection is necessary for trouble-free chromatography.Connecting incompatible fittings from
differentmanufacturers can result in leaks, poor peak shape, and increased void volume (Figure 1). Each
type of end-fitting has a unique seat depth or style. Generally, Restek, Valco
®
, Parker, and Upchurch
Scientific fittings are interchangeable; whereasWaters
™
, SSI, Rheodyne
®
, and Gasukura fittings are not
(Figure 2).
