Characteristics of Powder Metal for 3D Printing

Post by:

In Powder Metal (PM) applications such as 3D printing, the flow and packing behavior of PM is influenced by particle size and shape distributions. These properties can be measured in a statistically meaningful way using computer controlled scanning electron microscopy (CCSEM). In livetime, the SEM program detects a particle, defines its perimeter, calculates its size and […]

EBSD for Crystal Particle Analysis

Post by:

The analysis of a material’s crystallographic properties can provide a researcher with a wealth of information, including the identification, processing history, and much more. Although many techniques can be used to obtain various pieces of information, electron backscatter diffraction (EBSD) can give a more complete picture of not only what the substance is, but what […]

Presence of Mercury Indicates Potentially Counterfeit Version of Medication

Post by:

A client recently approached RJ Lee Group with a suspected counterfeit version of their patented injectable medication. Unlike the cloudy solution the company produces, the two samples provided were more translucent, almost clear. The client was concerned that the samples were either a counterfeit or contaminated version of their product, and asked our laboratory to […]

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 […]
