ProtumLink Extend 5cm (coming soon)

The ProtumLink 5 cm emitter-integrated column is designed for laboratories prioritizing high sampling throughput while maintaining the sensitivity needed for limited-input material. It is a reliable choice for rapid discovery and scouting experiments.

Even under accelerated conditions, the 5 cm format maintains sharp and stable peak profiles. At 1 µL/min, FWHM values remain consistently in the 3.1–4.1 s range across 5–15 min gradients, supporting confident peptide quantification and robust detection in high-volume workflows and QC environments.

With a usable flow range from 100 nL/min (nanoflow) up to 2000 nL/min (capillary flow), the column adapts well to different analytical needs. Its low backpressure enables operation at up to 1 µL/min even on pressure-limited systems, making it easy to transition between rapid screens, QC checks, and sensitive low-input analyses without changing hardware.

Extend columns are supplied in a Thermo EasySpray-compatible cassette format, enabling direct installation on EasySpray ion sources without additional emitter hardware or external high-voltage components. Electrical contact and emitter alignment are established automatically through the cassette interface.

The Extend format follows widely used heater geometries, enabling compatibility with common external column heating systems.

At the inlet side, an integrated liquid junction allows straightforward connection to nano-LC systems using standard 10-32 threaded female fittings, enabling fast column exchange while preserving zero-dead-volume performance.

This configuration supports reliable nanospray performance, easy system setup, and seamless operation on Thermo Orbitrap platforms equipped with EasySpray sources.
