This column offers:

Optimal separation performance

Obtain more than double the protein identifications than on a 40 cm packed bed column as demonstrated in this webinar.

Improved coverage

µPACᵀᴹ provides comprehensive coverage in single shot proteome analysis, nearing the mark of 10,000 identifications. Discover the results in our executive summary or webinar.

Extreme robustness

Each column has been manufactured by etching channels and pillar arrays out of a solid silicon wafer. The column is perfectly bidirectional and contains no particles or frits. This prevents blockages and retention time variation over multiple runs. Run your entire project on a single column.

Increased column to column reproducibility

Each column is manufactured using the same lithographic mask, making every column identical. Replace μPACᵀᴹs without retention time shifts. Obtain results over time and across laboratories, sufficiently consistent for big data analysis.

High flow rate flexibility

The column can be operated at moderate LC pump pressures up to 350 bar over a wide range of flow rates (100 – 1,000 nL/min).
