MicrOmics Emitters

Ideal for Single Cell Proteomics

MicrOmics Technologies LLC was founded to make advanced technologies available to scientists seeking to extend the capabilities of their LC-MS workflow, particularly for increased sensitivity and analysis of smaller samples (e.g., single-cell proteomics).

Stinger Emitters

MicrOmics Stinger emitters
Shown: 10 µm ID

These Stinger Emitters provide Optimal Performance Across the Nanoflow Regime (5-1000 nL/min). Fabricated using a proprietary chemical etching process, these nanospray emitters provide unprecendented performance.
