The Application Notebook 09-01-2019

High-resolution measurements of particles are of great interest in many fields of application. With ParticleScout, WITec has developed a tool that makes it possible to find, classify, and identify particles automatically.

In 1970, marijuana was designated a Schedule 1 drug, under the Controlled Substances Act, making it nearly impossible for laboratories to perform cannabis research. However, medicinal use of cannabis is now legal in Canada and 33 U.S. states.

Tribology-the study of friction, wear, and lubrication-is important in mechanical, electromechanical, and biological systems. Changes in materials due to abrasion, friction, lubrication, erosion, and corrosion result in failures of the moving components during use. These effects are usually minimized by careful surface finish design and lubrication. Recycling and refinishing surfaces can extend the lifetimes of components. By examining worn surfaces, better methods can be developed to prevent wear. This applications note uses infrared spectroscopy to study tribology changes in steel.

Moxi™ X-ray source is calibrated to within ±250 V over all settings between 5 to 50 kV. This impressive accuracy and precision is achieved spectroscopically, by measuring an X-ray spectrum's bremsstrahlung edge and storing correction high voltage offset information on each source.

Several pesticides were detected at parts-per-million levels on apple skin using a unique swabbing method and surface-enhanced Raman spectroscopy (SERS).

The analysis of organic chloride in crude is demonstrated per ASTM D4929 Part C using Monochromatic EDXRF (MEDXRF).

Mixtures of methanol in ethanol were investigated using an automated ATR accessory. The spectral bands of methanol and ethanol were evaluated showing the expected absorbance changes.
