The instrument is used for the quantitative analysis of optically active substances even in very small concentrations in blood or other solutions and, in particular, of glucose. It is a polarimeter which comprises: [A] (a) a light source (1), e.g. a laser or a laser diode or a conventional light source, the latter being used in conjunction with a polariser, (b) a measuring part for the sample (3) (c) a beam splitter (5) (d) an analyser (6) (e) one detector (7, 7<*>) each for analyzer and reference signal [B] (a) a differential amplifier (8) (b) a signal amplifier (9) (c) a power supply part and [C] (a) a device (10) for analog or digital display and/or registration of the concentration of the optically active substance and/or (b) a device for determining the rate of change of the concentration of the optically active substance and also a corresponding display device. The instrument is suitable for non-intrusive determination of, e.g., glucose in vivo as well as for determinations in vitro. <IMAGE>
