Why Electrochemically modulated liquid chromatography?

The carbon material's electrically conductive surface allows manipulation of interfacial properties (e.g., surface charge and oxidation state) to attract or repel permanent or transient charges of compounds. Read More

Electrically Conducting Carbon Materials for Electrochemically Modulated Liquid Chromatography 

NanoPak-E Features

  • Capture and release of charged analytes driven by applied voltage.

  • Pseudo-capacitive behavior allows for charge storage.

  • Ion exchange and reverse-phase separation mechanism.

  • Tunable size (diameter 5 µm to ≥ 1 mm) and porosity (pore size 10 -100 nm).

  • Durable.

    • pH stable 0-14.

    • Temperatures to 200°C.

Customer Benefits

  • Simplifies workflow; Lower or no use of ionic buffers for retention and release of the analytes from the stationary phase material; Lowers operational and maintenance costs.

  • Holds compounds with surface charges (e.g., DNA, RNA) even after removing the voltage; allows wash procedures.

  • Enables efficient, repetitive, selective separation of charged small (e.g. monophosphate nucleotides, peptides) and large (DNA, RNA, proteins) analytes.

  • Allows multimodal separation of analytes.
