Data confidence 70 medium
How this score is calculated

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.

Abstract

Extraction concentration of rhenium by a melt of tetraoctylammonium bromide in paraffin was used with the aim of preparation of calibration samples for roentgen fluorescent analysis. The calibration characteristics of the roentgen fluorescent analysis of rhenium is established, its linearity is evaluated, a limit of detection and a limit of quantification (determination) of rhenium are calculated. The maximal value of the relative total standard uncertainty of the calibration characteristic does not exceed 1.45%.ristic does not exceed 1.45%.
