Abstract

An analysis of the concentration of the individual components of a sample is obtained using a chromatographic analyzer where the concentrations of the individual components or the sensitivity of the detector to the individual components vary over a wide range. The sample is injected into a first chromatographic column and trace components of interest are eluted to a detector for measurement. The major components are backflushed, diluted, provided to a second chromatographic column and then eluted to a detector for measurement. The dilution of the major components ensures the linearity of the detector response. Analysis of both the trace components and major components is thus provided.
