Why is Degassing of HPLC Mobile Phase Necessary
Nov 18, 2013 · Vacuum degassing removes more than 60% of dissolved air. One option is to apply vacuum during filtration of mobile phase through 0.45 or 0.22μm porosity membrane filter. On – line vacuum degassing is available on most commercial available systems. Mobile phase is passed through porous polymer tubing placed in a vacuum chamber inside the HPLC.
