ProtumLink Connect 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.

Connect columns feature a pre-installed CaptiveSpray Inlet (CSI) adapter at the emitter end, enabling direct use on Bruker CaptiveSpray and CaptiveSpray Ultra ion sources without additional emitter hardware. 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 and preserving zero-dead-volume performance.

In Bruker configurations, grounding is applied through the liquid junction, ensuring proper electrical contact and stable electrospray operation.

This configuration provides a robust nanospray interface with minimal post-column dispersion, stable spray performance, and seamless integration with Bruker timsTOF platforms.
