The µPACᵀᴹ Trapping column can be effectively used to perform large volume (>5 µL) sample injections on µPACᵀᴹ analytical columns with minimal impact on the total analysis time. Its stationary phase support morphology is designed to perfectly match the analytical µPACᵀᴹ columns, with carefully selected dimensions and surface chemistry.
The trapping column comes in a duo- or five-pack.
The preconcentration of diluted samples or samples with very low peptide content into a sub-microliter trapping volume.
An effective removal of salts, reagents and contaminants that have no affinity for hydrophobic bonded phases increasing analytical column lifetime and improving spectral quality and detection sensitivity.
Depending on the analytical column flow rate, a 10 – 50-fold reduction of the sample loading time for high volume (5 – 20 µL) samples can be achieved.
Each trapping 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.
The trapping column can be operated at flow rates from 0.1 – 20 µL/min — corresponding column backpressures of up to 40 bar. The maximum operation pressure is 350 bar.
