Emitter Technologies
Innovative emitter geometries designed for stability, sensitivity, and lasting performance.
ProtumLink’s column design combines the mechanical robustness of separate-emitter systems with the sensitivity and electrospray stability of integrated emitter technologies. The use of homogeneously tapered emitters stabilizes the packing bed and preserves a uniform emitter geometry, ensuring consistent performance across extended operation. This integrated approach reduces mechanical stress and signal variability, resulting in exceptional robustness, longer column lifetime, and sustained analytical precision.
