Prototyping of a Microfluidic Modulator Chip and Its Application in Heart-Cut Strong-Cation-Exchange-Reversed-Phase Liquid Chromatography Coupled to Nanoelectrospray Mass Spectrometry for Targeted Proteomics
Original language description
A novel multilayer modulator chip offering a robust miniaturized interface for multidimensional liquid chromatography has been developed. The thermoplastic microfluidic device comprises five tailor-made functional layers, and the chip is compatible with commercially available switching-valve technology. The modulator chip allows for robust ultrahigh-pressure operation up to 65 MPa. Peak-dispersion characteristics of system peaks were assessed directly at the valve outlet by monitoring fluorescein injection profiles with laser-induced fluorescence detection. Integration of a microporous monolithic mixing entity in the microchannels significantly narrows the resulting peak profile. Proof-of-concept of the applicability of the microfluidic modulator chip is demonstrated in a heart-cut multidimensional strong-cation-exchange-reversed-phase liquid chromatography proteomics analysis workflow coupled to nanoelectrospray mass spectrometry for the target analysis of Glu-1-Fibrinopeptide B spiked in a protein digest mixture of bovine serum albumin.
