Analysis of Pharmaceutical Residual Solvents Using Comprehensive Two-Dimensional Gas Chromatograhy

Analysis of Pharmaceutical Residual Solvents Using Comprehensive Two-Dimensional Gas Chromatograhy

Christina M. Crimi;Nicholas H. Snow
January 1st 2008

Comprehensive GCxGC was employed for the separation of ICH and USP 1, 2, and 3 pharmaceutical solvents. The significantly improved peak capacity in GCxGC allows a single method for any combination of solvents and mitigates interference due to impurities in the solvents, diluents, analyte matrices, and from column or septum bleed, through the increased separation space.
