The Right Instrumentation and Techniques for Your Solution

Instrumentation and Techniques

Instrumentation and Techniques

Accurate analytical results depend on many levels of expertise including using the right instrument, the correct sample preparation, and the best-suited technique. When that combination also includes expert and clear interpretation, you have results that not only provide answers, but answers that you can understand. For more information, please call us at 1.800.860.1775, option 5.

Our materials experts are always ready to discuss the instrumentation and the techniques available and how they apply to your situation based on the results you are looking for. In addition to standard analytical chemistry and optical microscopy services found in our Laboratory Testing Guide, we use the following instrumentation and techniques when seeking resolution to our customers’ problems.

Customizable Automated Techniques

In response to customer requirements, we have developed laboratory automation techniques that reduce the time needed to analyze large numbers of particles to provide results more quickly while still continuing to maintain data quality.

Computer-Controlled Scanning Electron Microscopy (CCSEM)

CCSEM is an automated analytical technique that combines a scanning electron microscope (SEM), x-ray analyzer (EDS) and software-controlled digital scan to quickly locate, size and characterize large numbers of individual particles and group them based on their elemental composition and shape. A primary use for this technique is in the automated analysis of gun shot residue (GSR) particles. This technique can be customized based on the application needed.

Automated Steel Cleanliness Analysis Tool (ASCAT)

This technique is based on CCSEM and is primarily used as a quality control tool for characterizing inclusions in steel that have been trapped during the solidification process. The automated analysis quickly identifies and characterizes the steel inclusions but can also be customized based on the application needed.
