87. chiral inversion Enzyme- or chemically-mediated conversion of one enantiomer to its antipode (opposite enantiomer) with no other change in the molecule.
88. chromatogram In chromatographic analyses, a graphic display of chromatographic output, typically showing the response as the y-axis and time as the x-axis.
89. chromatographic column Essential component of a liquid or gas chromatographic system, containing the stationary phase and through which flows the mobile phase. Separation is typically effected through partitioning, adsorptive, electrostatic or affinity-based interactions between the analyte in the mobile phase and the stationary phase.
90. chromatography A system using a stationary phase (see ‘Chromatographic column’) and a mobile phase to effect separation of molecules in a given sample.
