| 摘要 |
Automatic apparatus is described for the analysis of two or more constituents of interest present in widely varying concentrations in liquid samples by a common analytical device or detector selective with respect to such constituents. The liquid samples are directed successively along the apparatus as in initial stream, which is divided into two or more streams. The two or more streams are differentially diluted and reacted, so as to be accommodated by the common detector, prior to being passed alternatively and in succession to the common detector.
