  • Preparation of samples for XRF using flux and platinum crucible
    Patent number: 10107551
    Abstract: A method of of preparing samples for XRF using a flux and a platinum crucible includes forming the flux into a free-standing crucible liner. This may be achieved by mixing lithium borate particles with a liquid to form a paste; placing the lithium borate paste onto the inner surface of a mould; and after drying removing from the mould and firing the lithium borate paste to dry the lithium borate to form a free-standing crucible liner. The liner may be placed within a platinum crucible and then a sample placed in the liner. The temperature of the crucible is raised to a sufficient temperature that any oxidation reaction takes place before taking the temperature above the melting temperature of the flux to melt the crucible liner and dissolve the sample into the flux. The crucible can then be cooled and XRF measurements made on the sample.

  • Method of making a standard
    Patent number: 9658352
    Abstract: A measurement standard suitable for measuring amounts of certain elements in pharmaceutical excipients is described. A reference standard is dissolved in a solvent, for example acetone, and mixed with a pharmaceutical excipient such as cellulose, lactose or calcium carbonate. The solvent is then evaporated to provide a dry standard.
