Use of inorganic fiber filter paper in gravimetric microanalysis

Microchimica Acta Aims and scope Submit manuscript

Summary

Filter mats for filtersticks, filter tubes, andGooch crucibles are easily prepared with the use of filter papers made of glass fibers or fibers of vitreous silica. The reliability of such filter mats for the purpose of quantitative micro analysis has been tested with silica fiber paper which is somewhat more difficult to use, but permits high ignition temperatures.

Zusammenfassung

Filterstäbchen, Filterröhrchen undGooch-Tiegel können in einfacher Weise mit beständigen Filterschichten aus anorganischem Filtrierpapier, das aus feinen Glasoder Quarzfäden hergestellt ist, versehen werden. Die Eignung solcher Filterschichten für Zwecke der quantitativen Mikroanalyse erscheint durch Versuche mit Quarzfaserpapier erwiesen, das schwieriger zu handhaben ist als Glasfaserpapiere, dafür aber hohe Glühtemperaturen zuläßt.

Résumé

On prépare aisément avec de la soie de verre ou de la silice vitreuse des plaquettes filtrantes pour baguettes, tubes et creusets de Gooch. De telles plaquettes ont été soumises à l'épreuve pour la micro-analyse quantitative avec de la laine de silice qui est un peu plus difficile à employer mais permet des températures d'ignition plus élevées.
