Incredibly stable retention times
Retention times were highly consistent across multiple columns and injections, with minimal drift observed – this level of chromatographic reproducibility is critical for large-scale and longitudinal studies.

Stable peptide retention times across different columns. Ten peptides were selected and their retention times assessed across all columns from 3 HeLa tryptic digest injections (250 pg) on Aurora Rapid 8 cm × 75 µm columns, using an 80 SPD method. Samples were run on a Vanquish Neo and Bruker timsTOF Ultra 2 mass spectrometer. Raw data were analyzed in Spectronaut version 19.8 with the “Match between runs” feature disabled.
Column backpressure stability and protein group IDs over extended use
The figure below shows backpressure at 8 minutes over more than 650 QC runs using 60 SPD method, with only a gradual increase from 130 to 175 bar and consistently high unique protein group IDs. Complex samples were analysed between QC runs, highlighting column’s robustness and suitability for high-throughput proteomics.
