It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
The advantages of atomic-emission determination (validated for photoelectric spectra recording) of arsenic, tin, antimony, thallium, gallium, germanium, and indium in rare metal ores and products of their processing are demonstrated. Replacement of the spectrum recording system of a DFS-8-3 diffraction spectrograph by MAES analyzer transforms it into a modern spectrometer capable of rising labor efficiency of the analytical laboratory.
