Bruker-PepSep Tapered nESI Emitters

PepSep manufactures specialty Stainless Steel, and Fused Silica emitters to optimize nanoflow proteomics workflows. The Fused Silica and Stainless Steel Emitters with 1/32” PEEK sleeve, can be used in custom made setups. The emitters are polished with fine diamond films to give a perfect tapered tip. All emitters are available in different lengths and widths, and feature an outer diameter (OD) of 150 µm.

After having manufactured metal and fused silica emitters, Pepsep also introduced a set of the bespoke “integrated Liquid Junction” emitters (to combine with our ESI-Sprayers). This last development was done in collaboration with Evosep Biosystem, who use these sprayers with their Evosep One system. The Bruker-Pepsep 1893517 Stainless Steel Emitters are a one-to-one replacement for Thermo Scientific™ ES542 emitters.
