<p>1316251 Automatic analysis of sample streams TECHNICON INSTRUMENTS CORP 30 Sept 1970 [1 Oct 1969] 48271/69 Heading B1X Automatic analysis of two or more constituents present in a fluid sample in different concentrations is performed by forming two (or more) parallel streams of the sample in lines 12, 14, adding diluent to at least one stream to effect differential dilution, e.g. via pipe 11, and feeding the streams independently via a valve 20 to a common analyser 22, e.g. a spectrometer, whilst one stream is analysed the other may pass the drain 24. Standard reference solutions are added via lines 28. The system is rinsed between samples.</p> |
