Title: Process and apparatus for compensating for the differences arising from the density variation of liquids
IPC: G01N23/06
Filed: 1966-06-10
Abstract: 1,148,309. Irradiating liquids. MAGYAR ASVANYOLAJ ES FOLDGAZ KISERLETI INTEZET. 10 June, 1966 [10 June, 1965], No. 26059/66. Heading H5R. In the process of subjecting a liquid to radiation analysis, wherein the variations of density of the sample during measurement are compensated for by the variation of the thickness of the sample measured, the deviation from the initial density of the sample is transformed into a weight difference by suspending a vessel of constant volume capacity containing the liquid sample to be tested from one arm of a balance beam initially in balance with the weight of the suspended sample, an elastic element being connected at one end to a predetermined point on the balance arm and at the other end to a point independent of the balance so that the elastic element operates against the load exerted by the sample, and the liquid layer thickness passed through by radiation from a radiation source is changed according to the movement of the balance beam as controlled by the deflections of the elastic element. An apparatus suitable for this process is shown in Fig. 2 and comprises a balance M to one arm of which is attached one part E of a constant volume vessel, the other part A being supported independently of the balance arm and being connected to E through a pipe line, e.g. two interpenetrating tubes, the external one being connected to vessel A, which pipe line allows a frictionless displacement of vessel E with respect to vessel A. A radiation detector D is supported independently of the balance, and vessel A and a radiation source F is supported in a closed tube C coaxial with vessel E and an elastic element R e.g. a coil spring, leaf spring, rubber spring or air cushion is fastened to and is preferably displaceable along the beam. Preferably tube C is filled with gas e.g. air, and the lower end of the tube closed by radiation permeable plate Z is always submerged below the liquid level of vessel A, the bottom of which is constructed of the same radiation permeable material. The apparatus may be arranged so that the variation from the mean in liquid thickness between the bottom of tube C and vessel A amounts at most to 10% and preferably 2-3% of the average distance between the detector and the radiation source in either direction. An inlet orifice for liquid may be provided in the base of vessel E and an outlet in the top of vessel A, both orifices being on the opposite respective sides of vessels A and E to the pipe line.
