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; whereas Waters, SSI, Rheodyne®, and Gasukura fittings are not
(Figure 2).
Our wrenchless universal 10-32 PEEK™ column connector (cat.# 25015, page 54) can be usedwith any
style of end fitting, and all
1
