Analysegerät und Verfahren zur Analyse von flüssigen Proben

A fluid injection analysis apparatus (10) and method uses a liquid stream (13) a detector (12), and a computer (11) which operates to observe properties in the composition of the fluid stream and compare detected data from observed samples with standards and in accordance with parameters established by calibration, calculate the characteristics of the observed samples. An integral but segmented liquid stream (13) flows through the analysis apparatus (10) to provide liquid segments of observed sample and reagent. The detector (12) scans data from the samples at the interface between these segments, and information relating to the composition at the interface is analyzed in accordance with a mathematical model that permits comparison of the detected data from successively observed samples with standards and thus determines the characteristics of the samples. The information includes values such as electrical conductivity, concentrations, and compositions of the samples and the operation rapidly and precisely analyzes and records multiple samples.
