    摘要: There is described an apparatus and method which permits accurate weighing and/or measuring of solid particulate matter. The invention may be utilised to enable a hollow structure (1) such as a container (for example a tube) to be at least partially filled with a pre-determined volume or weight of solid particulate matter, such as powder, in an accurate and reproducible manner. In particular there is described a method of measuring out a specific volume and/or weight of particles. The method comprises the up-take of a pre-determined amount of particles into a transfer vehicle (4), movement of the particles into the tranfer vehicle (4) being controlled by pressure (5, 6); and the volume of the transfer vehicle (4) dictating the amount of particles taken up. In this manner a specific volume of particles may be accurately taken up into the transfer vehicle (4) and the volume may be calculated to give a certain weight of particles, depending on the density of the particles in question. The particles taken up in the transfer vehicle (4) may be expelled therefrom, when required, by alteration of the pressure (5, 6).

    摘要: A capillary flow cell in which a capillary (9) partially extends along the optical path of the cell and has its two end portions (12,13) bent to achieve an essentially Z-shaped configuration. A template (1) has a central bore (2) in which the middle part (11) of the capillary (9) is positioned. A method of manufacture of this capillary flow cell comprises the steps of a) inserting a capillary in a central bore of a template, b) heating the capillary immediately outside the bore to soften the capillary material c) bending the two ends to achieve an essentially Z-shaped or U-shaped configuration. i

    摘要: The isotopes of zirconium can be partially or completely separated by loading an essentially anhydrous alcoholic solution of an ionic compound of zirconium onto a cationic exchange resin with pentavalent phosphorus derived active groups which serves as the stationary phase of a chromatograph, eluting the compound with an essentially anhydrous alcoholic solution of hydrogen chloride and collecting distinct elution volumes representative of each isotope. In a preferred embodiment, the active groups of the cation exchange resin are derived from di-2-ethylhexyl phosphoric acid, tri-n-octyl phosphine oxide or tributyl phosphate and the chromatograph is of a type, such as a continuous annular chromatograph that it can be operated in a continuous, steady state manner.
