    Constant current source for automatic coulometric titrations
    (Australian Atomic Energy Commission, 1958-03) Palmer, AR; Pryor, AW
    A simple, but versatile constant current source for automatic coulometric titrations is described. The unit is suitable for use with a commercial automatic pH titrimeter and will accommodate wide variations of mains voltage and load resistance. Coulometric titrations may be carried out "fast" or "slow" with a choice of four current ranges (2-37 mA) for titrations up to or near the end point. A slow "1mA" range is available for approaching the end point and the titration of microgram amounts of material. The automatic pH titrimeter provides for automatic change fast to slow generation of reagent and for stopping the titration at selected end points. The utility of the equipment has been demonstrated by the estimation of chromium with electrogenerated ferrous iron. The unit should be suitable for many other coulometric titrations.

    The determination of fission product levels in HIFAR heavy water
    (Australian Atomic Energy Commission, 1968-01) Palmer, AR; Porritt, REJ
    Methods for the determination of Ba-140 and I-131 are described. These methods are suitable for routine monitoring of fission product levels in the HIFAR heavy water circuit. The results obtained over a four-month period are presented and discussed.

    Studies in computer coupled radiochemical analysis - Part 1. peak location and peak energy measurement in scintillation spectrometry
    (Australian Atomic Energy Commission, 1968-02) Palmer, AR
    A FORTRAN IV (Level H) programme is described which locates photopeaks in the output of a multichannel analyser scintillation spectrometer assembly. The programme is particularly useful for processing the output of large capacity analysers working in conjunction with a high resolution Ge(Li) detector.

    The thorium-apans complex: a spectrophotometric study
    (Australian Atomic Energy Commission, 1958-02) Palmer, AR
    The analytically useful complex formed by thorium and APANS [1-(o-arsonophenylazo)-2-naphthol-3:6 disulphonic acid] has been studied by a spectrophotometric method. The complex is shown to be of the 1:2 type and it equilibrium constant measured.
