Astimex Standards <\/strong>produces polished\u00a0metallic element<\/a>,\u00a0rare earth element, mineral and synthetic compound\u00a0standards<\/span> suitable for\u00a0Electron Microprobe<\/strong>\u00a0and\u00a0Scanning Electron Microscope X-ray Analysis<\/strong>. They are also suitable for\u00a0Laser Ablation Mass Spectrometric Analysis<\/strong>.<\/p>

Among our\u00a0“Package mounts”\u00a0(or standards for microanalysis), all naturally occurring stable elements are represented, with the exception of the noble gases. The pure metals are all of those which are stable and solid at room temperature and which can be prepared in a polished form. Some of them are more suitable than others for this type of use, and some degree of oxidation or failure to polish well may be expected in certain cases. The purity of the metals is always better than 99%, and most of them more than 99.99%. Details of the individual purities and source supplier are given with each purchase, or on request. Even the light element range, difficult to access by X-ray analysis is given complete coverage.<\/p>

The\u00a052 minerals and compounds<\/a>, for which analyses are provided on purchase, are chosen to give comprehensive coverage of the elements, especially those which cannot be mounted in the pure form. These minerals are carefully selected on the basis of their homogeneity within and between grains, and have been analyzed quantitatively at the Universities of Toronto or Alberta. Some of the materials are synthetic and, after experimental confirmation that they contain no detectable impurities, ideal compositions have been assigned to them. Between the minerals and metals, most naturally occurring elements are represented in major concentrations, with the only notable exception being the noble gases. Metals and minerals can be mounted and polished separately or together, though there are certain recommended groupings, referred to below as\u00a0Package Mounts, which are held as stock items, and for which the\u00a0prices<\/a><\/span> are set.\u00a0<\/p>

The mount sizes are 25mm diameter (1 inch) and 6mm thick non-magnetic stainless steel. See the various layout patterns and contents of the Package Mounts. The Rare Earth Elements are grouped together in a single mount as this is convenient for geochemical work, and as several of these are unstable in the metallic form, fluorides are used as an alternate. The mounting medium used in all mounts is epoxy resin. The metals and minerals are most economically purchased in the Package Mounts<\/a>, but in the case that a special selection of items is made, the\u00a0charge is on a per item<\/a><\/span> basis. Minerals and synthetic materials other than those listed may be available on request.<\/p>

Standard material can also be purchased as “loosies” for self-mounting and polishing, please see our selection here<\/span><\/a>.\u00a0<\/p>
