Columns and Emitters

Evosep columns and emitters deliver sharp symmetrical peaks robustly and reproducibly over thousands

Evosep emitters are designed with either stainless steel or fused silica and come with integrated liquid junctions for easy zero dead volume, finger tight connections in our source adapters.

Emitters are available in Endurance and Performance versions. The default is an Endurance ID 30 µm stainless steel emitter (EV1086). The fused silica emitters are available in ID 20 µm (EV1087) and the ID 10 µm Performance version (EV1111).

All the columns come default with fittings for their own emitters and spray adapters, but when those are not appropriate, you can find open-ended versions (marked OE) of their columns for connecting to your own spray solutions.
