CoAnn Pulled Emitters

 Pulled and Sharpened Tips for proving maximal ESI MS Sensitivity.

Since autumn of 2019 MS Wil has worked with CoAnn Technologies for the supply of their integrated and separated emitter columns and as of recently their pulled Fused Silica emitters. CoAnn started producing these pulled emitters for use with their separated capillary columns and we have a number of customers in Europe who have been successfully using them.

These emitters have very thin walls to maximize ESI sensitivity and sleeve protectors for their easy/safe use. The wide range of ESI emitters tube inner diameters and orifice sizes allows for optimal match of emitters to various dimensions of nanoLC columns and different scales of direct liquid infusion measurements in varieties of mass spectrometry applications.
