Introducing the NanoLC-Ultra family of high pressure HPLCs that delivers superior gradient precision at pressures up to 10,000 psi.

The next generation NanoLC system from Eksigent promises to deliver high resolution separations, combined with excellent reproducibility, resulting in improved identification of low abundance peptides/proteins with nanoLC-MS.

The higher pressure capability of the NanoLC-Ultra platform allows the use of longer columns and/or columns packed with smaller particles for higher resolution separations of complex (digested) protein samples. Moreover, the NanoLC-Ultra family features self-priming and self-purging pumps for easier changing of solvents, and a temperature-controlled column compartment for maintaining exceptional retention time reproducibility.

Eksigent’s proven Microfluidic Flow Control™ (MFC) technology guarantees reliable and reproducible results, while integration with major mass spectrometer software packages makes the system a seamless addition to almost any nanoLC-MS workflow.

A range of different NanoLC-Ultra system configurations are available for various proteomics applications—from single gradient systems for direct sample injection, to dual gradient systems for multidimensional separations, and dual column set-up for increased throughput.
