In a new article, researchers provide an overview of sample preparation techniques and information on routine sample types that may be encountered in forensic toxicology cases. As analytical ...

For XRF analysis, fused bead creation via fusion provides a nearly perfect, homogeneous sample representation. This method is ideal for solid samples. Gas and electric fusion machines can be used to ...

Sample preparation will vary depending on the sample, imaging mode, and size of desired images. You will likely need to do a literature search to find the preparation best for your sample. Smaller ...

Simplification, automation, and disposability were the key themes at Knowledge Foundation’s recent “Sample Prep” conference in San Diego. Speakers indicated that researchers’ quest for “the next big ...

Evaporation is an endothermic process undertaken by all liquids. This physical state change occurs when surface molecules gain sufficient kinetic energy to overcome the enthalpy of vaporization. Such ...

Proper quality measures are vital in all areas of clinical laboratory testing to prevent or avoid carryover between samples, as well as to minimize the risk of false-positive results. The sample ...

All NanoESCA measurements are extremely surface sensitive. As an approximate guide, XPS measurements probe up to 10 nm of the sample surface, ARPES and UPS measurements probe between 0.5 and 1 nm, and ...

The images produced with a cryo-electron microscope can only be as good as the sample that goes into it. That's why Jiro Usukura, at the Structural Biology Research Center, Nagoya University, says ...

In cement sectors, including other industries, sample preparation is a vital step to guarantee that XRF analyzes are truly effective. To attain reliable and accurate XRF results that adhere to the ...
