PepSep Sprayers

Novel ways to make nano electro spray set-ups that are easy to work with.

Thermo nanoSpray Flex and EasySpray ion sources

In our collaboration with the Danish company PepSep, MS Wil provides novel ways to make nano electro spray set-ups easy to work with. In the last few years PepSep have developed two new “Sprayers” and emitters.

The PepSep sprayers and emitters make use of an unique integrated Liquid Junction solution, where a metal electrode is mounted on the end of an emitter. The Liquid Junction now works, as a way to transfer the High Voltage to the liquid flow, but also positions the emitter inside the sprayer. The sprayer comes in two version, which are built to either fit the column entry of the EasySpray source or can be mounted on the bracket that sits on the XYZ-manipulator of the nanoSpray Flex ion source as depicted below.

Finally a column or transfer line can be connected to the sprayer using a Viper®-like (1/16”) connector. This connector makes a zero dead volume connection to the end of the emitter/liquid junction, were a film of liquid between the parts conductions the electrical current and the metal liquid junction itself is not in the eluent flow.
