Nanoelectrospray emitters
nESI emitters with a 4 ± 1° taper
Precision-pulled nanoelectrospray emitters for proteomics, with inner diameters from 10 to 20 µm and a sharper tip for higher ionization efficiency.
Sharper tips
Better ionization, more identifications
The sharper the angle, the higher the ionization efficiency. Our emitters deliver up to 2.5 times more peptide and protein identifications than standard emitters, and a nanoparticle coating reduces clogging in complex samples.
- Inner diameter options of 10 and 20 µm
- Compatible with Thermo™ EASY-Spray™ sources and nanoViper™ fittings
- Zero dead volume, no tools needed
- For direct infusion or LC-MS
Improved sensitivity
Stable signal across hundreds of runs
QuickFit™ emitters keep their sensitivity and signal stability run after run, so your identifications stay high from the first injection to the last.

Quality control
Every emitter, inspected one by one
Our own vision-based software measures each tip angle with sub-degree precision. More than 95 % of our emitters fall inside the specified taper range, and every one is inspected and tested before it ships.
Questions
Frequently asked questions
We offer 10 and 20 µm. Both are designed for high-sensitivity proteomics; tell us your flow rate and column and we will recommend one.
No. The emitters connect with zero dead volume to EASY-Spray™ sources and nanoViper™ fittings without tools.
Yes. They work with your existing columns as well as with Montara integrated systems.
