Selecting the Right Crushing Equipment

Crushing equipment is central to a wide scope of sample preparation tasks, impacting all manner of workflows from the lab bench to the production line. Selecting the right crushing equipment for the job is subsequently critical. At XRF Scientific, we supply a wide range of laboratory crushers primarily used for elemental analysis. In this article, we will outline some of our crushing equipment to help you choose the best tool for the job.

The Basics of XRF Crushing Equipment

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 mixt...

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...

How ICP Spectroscopy is Applied to Archaeology

Inductively-coupled plasma (ICP) spectroscopy has provided archeological researchers with an ideal resource for quantitatively and non-destructively determining the elemental composition of a sample. ICP spectroscopy only requires small surface samples to acquire detailed information relating to sample trace elements and the provenance of geochemical analytes. This is due to the outstanding sensitivity of ICP mass spectrometry equipment, which is designed to perform sample analysis and provide data pertaining to the concentration of metals and select non-metal materials present in the analyte. ICP spectroscopy can accurately quantify the presence of elements with concentrations below the parts per million (ppm) range.

This extreme level of precision makes ICP spectroscopy uniquel...
