ProtumLink Extend 15cm

The 15 cm emitter-integrated column provides an optimal balance between gradient time and separation space. It enables fast to mid-length gradients while maintaining high peak capacity and confident proteome coverage.

At 500 nL/min, FWHM values of ~3.5–4.6 s across 15–45 min gradients demonstrate that separation efficiency is preserved even under accelerated conditions. This format delivers strong identification depth without extending runtimes unnecessarily, making it a versatile choice for both discovery and quantitative workflows.

Operating across 100–1000 nL/min, the 15 cm format maintains resolving performance across a wide range of gradient lengths. It represents the practical midpoint between rapid screening formats and deep-resolution columns.

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.
