ABSTRACT:
A quantitative analysis of the concentration of the individual components in a sample is obtained using a chromatographic analyzer without the need to calibrate the chromatographic analyzer detector. Two chromatographic analyzer systems are utilized to analyze two identical samples using two different carrier fluids. The difference in the response of the two chromatographic analyzers is proportional to the difference in the properties of the two carrier fluids being measured by the chromatographic analyzer detectors and the concentration of the desired component of the sample. Because the proportionality does not involve the property of the individual sample component being measured by the chromatographic analyzer detector, it is possible to obtain a quantitative analysis of the concentration of the individual components of the sample without the need to calibrate the chromatographic analyzer detectors.
