Optical emission spectroscopy is a powerful tool for monitoring plasmas in situ, enabling process optimization and control. It is used to measure the energy difference between excited and ground states…
Read MoreInfrared and Raman are both categorized as vibrational spectroscopies, which broadly speaking, measure the same basic material properties. Namely, they provide a molecular fingerprint by determining the vibrational energy levels…
Read MoreRoundup Experiment In this experiment, we tested low concentrations of glyphosate with a special variable path length dip probe with a narrow tip to measure the chemical’s absorbance. We tested…
Read MoreIn this experiment, we tested the color change of three pH indications from a basic initial state to an acidic final state. The three indicators used were universal indicators, bromocresol…
Read MoreAllura Red is a red powdered azo dye that is used in food, cosmetic, drug, textile, and, paper industries. Allura Red is known by many names, but the most familiar…
Read MoreEarlier this year, we had the opportunity to analyze an extensive sampling of garnets from around the world, courtesy of collections from Dan Zellner of DanZ Rockshop and Nathan Robey,…
Read MoreClimate change and population expansion have a direct impact on agriculture. An increasing number of people need to be fed but changing weather patterns can cause complete crops to fail.…
Read MoreFor over 120 years, agriculturalists have been aware of the importance of soil testing, particularly elemental analysis, to ensure the health and productivity of crops. Historically this has been accomplished…
Read MoreSpectroscopy Methods for the Gemology Industry Spectroscopy has been long used in the gemology industry for characterization and identification, with nearly every known spectroscopic method playing a critical role. Transmission…
Read MoreQuick and accurate quantification of protein content is critical for modern biology, biochemistry, and biophysics labs worldwide. Not only are researchers interested in detecting the total protein content, but they…
