Clarity Control Module DEMO GCXGC MODULATOR

Význam tématu

Comprehensive two-dimensional gas chromatography (GC×GC) with modulation significantly enhances peak capacity and resolution in the analysis of complex mixtures. Modulation, the periodic trapping and release of analytes between two columns, sharpens chromatographic peaks and allows more reliable quantification of trace-level components.
