Outlining the Crushing Equipment Available from XRF Scientific

To accurately assess the x-ray fluorescent (XRF) properties of a dry, organic sample through XRF spectrometry, the sample must first be prepared with a fusion flux of either lithium metaborate (LiBO2), lithium tetraborate (Li2B4O7), or a mixture of the two with suitable oxidizing additives. The homogeneity of these mixtures can have a significant impact on results accuracy, which is why eutectic flux mixtures are prepared at varying ratios with distinct physiochemical structures. Following eutectic mixture selection, the dry analyte must be reduced to a suitable consistency for fusion using crushing equipment.

Laboratory crushing equipment typically pulverizes dry geological samples using mechanically agitating jaws or gyrating plates. ...

XRF Sample Preparation Method Development

XRF sample preparation is a precise methodology of preparing analytes for elemental analysis. Organic samples must be uniformly homogenized using hydraulic crushing or pulverizing equipment, before they are dosed with a eutectic flux mixture and prepared through fusion techniques. This sensitive, multi-component procedure enables researchers to acquire as close to near-homogenous x-ray fluorescence data from a sample as possible, with applications ranging from geological exploration to forensics analysis. These high-precision applications require results that are actionable with negligible margins of error.

Expert method developments for XRF sample preparation routines enable operators and researchers to acquire appropriate equipment and treatment chemicals for distinct specifica...
