ZipChip Interface for Mass Spectrometry

ZipChip System: a seamless workflow for CE/ESI-MS analysis of biological samples

Integrate capillary electrophoresis (CE) and electrospray ionization (ESI) into a single microfluidic device to rapidly prepare, separate, and electrospray biological samples directly into your Thermo Scientific mass spectrometer. The portable size ZipChip Interface directly mounts onto select models of Thermo Scientific mass spectrometers, and creates a seamless CE/ESI-MS workflow that offers fast CE separation, nano-spray level sensitivity, and HRAM spectrometry for the characterization of intact proteins, antibody drug conjugates (ADCs), antibody subunits, peptides, and metabolites.

Sample preparation

  • Minimal or no sample preparation is required for typical biological samples.
  • Desalting occurs on the chip to clean up high salt concentrations, residual detergents, and other production chemicals.

Capillary electrophoresis separation and electrospray ionization

  • Analytes separate due to differences in electrophoretic mobility, which is simply a function of the charge and size of the analyte.
  • Analytes are electrosprayed directly into the mass spectrometer through the ESI emitter on the corner of the microfluidic chip.
  • Stable, sensitive nano-spray ensures the best combination of sensitivity and robustness.

Analysis time

  • Entire CE/ESI-MS analysis can be complete in only 2-3 minutes for most biological samples which can significantly improve lab productivity.

In this webinar, the benefits of integrating cutting-edge microfluidic technology with capillary electrophoresis (CE) and electrospray ionization (ESI) for enhanced mass spectrometry (MS) analysis is presented. This novel CE-ESI MS approach offers improved sensitivity and resolution, and increases sample throughput with minimal preparation time.
