Trajan Tapered Emitters

Maximize reproducibility with tight-tolerance fused-silica and smooth surface finishes

After a long process of modelling and experimenting, Trajan managed to develop their new robust nESI-emitters. Trajan tapered nanospray emitters are designed for those seeking maximum reproducibility, reliability, and sensitivity in their ESI-MS workflows. Available in a wide range of lengths, inner diameters, and coating options make Trajan’s tapered emitters suitable for most source configurations.
