BTX™ III Benchtop XRD Analyzer for Fast Mineral Identification

The BTX III X-ray diffraction (XRD) analyzer from Olympus Scientific Solutions offers fast, dependable quantitative mineralogy of both major and minor components in a small, benchtop design.

The BTX III analyzer features an exclusive small sample holder to offer a lightweight and almost maintenance-free substitute to traditional XRD. This standalone instrument operates without the need for water cooling, compressed gas, a secondary chiller, or external transformer, thereby minimizing the cost of ownership. Operators can directly link the XRD instrument to any device using Ethernet or wireless capability.

The XRD tools of Olympus Scientific Solutions are driven by intuitive SwiftMin® software to streamline the workflow with a single dashboard, easy data export, preset calibrations, and automatic data transfer.

Better Speed and Sensitivity Power Swift Decisions

Intuitive and robust software is coupled with better quality X-ray detectors for faster analysis times, improved sensitivity, and more consistent results.

  • Updated X-ray detector hardware works faster and provides more intensity, resulting in lower LODs.
  • SwiftMin® automated phase ID and quantitative software offers real-time data directly on the XRD analyzer, so users can make quick decisions with confidence.

Sample Preparation is Made Easy

Using traditional X-ray diffraction instruments, a large batch of samples must be thoroughly ground and pressed into a pellet to guarantee an adequately random orientation of the crystals.

On the other hand, the small vibrating sample holder used in the BTX III convects all particles inside the sample chamber, which ensures data is almost free of orientation effects. Consequently, the instrument requires just 15 mg of sample, which can be easily obtained using the supplied sample kit.

The BTX III instrument offers quick mineral identification for a wide variety of applications, such as those discussed below.

Mining and Ores

Iron-rich ores: Iron-rich ore can be analyzed even when specific phases are entirely absent.

  • Hematite
  • Goethite
  • Quartz
  • Magnetite

Potash: Potash can be analyzed for phase identification and semi-quantitative analysis of identified minerals, including:

  • Leonite
  • Sylvite
  • Langbenite
  • Halite

Limestone and cement: Users can easily conduct quantitative XRD analysis of basic minerals related to limestone. When the quarry has different levels of dolomite, the analyzer rapidly identifies this mineral in the range of 0.5% to 9%, with an error of just 0.02%.

  • Calcite
  • Alpha-quartz
  • Dolomite
  • Asbestos minerals

Calcite in coal: Users can quantify calcite (CaCO3), a mineral known to reduce the efficiency of the raw material fuel in a coal-fired plant, to enhance efficiency and minimize carbon emissions.

Oil and Gas

Well logging/mud logging: Users can carry out mineral identification and quantification on shale cuttings in the field for quick feedback at geosteering and horizontal drilling areas. They can streamline “chasing the vein” of specified mineral strata.

  • Clays
  • Pyrites
  • Carbonates
  • Silicates

Pipelines: The energy-sensitive detector facilitates ideal peak-to-background performance to detect and measure corrosion materials on pipelines. Concurrent XRF measurements allow elemental constituents to be rapidly identified.

  • Wustite (FeO), goethite (FeO(OH)), hematite (Fe2O3), and pyrite (FeS2)
  • Aragonite (CaCO3) and calcite (CaCO3)

Mine tailings: Users can easily re-examine mine tailings to identify mill performance or assess historical projects.

  • Quick identification of fake pharmaceuticals
  • Rapid, nondestructive fingerprinting of drug formulations and precursors
  • The presence and quantity of inactive and active substitute or foreign ingredients can be tested
  • Rapid XRD analysis helps guarantee patient safety and protects genuine pharmaceutical manufacturers’ branding
