Increase productivity and profitability in environmental analysis with IC
Nearly every chemist begins his or her path under the guidance of trained professionals, learning the correct way to implement the scientific method and to handle themselves safely in the laboratory. I am no different; I obtained my doctorate in Analytical and...
How Mira Became Mobile
Handheld Raman spectrometers are truly like no other analytical chemical instruments. All spectrometers (e.g. IR/NIR, UV-Vis, GC/MS, and Raman) rely on interactions between matter and energy and include detectors that collect information about resulting atomic and...
How to determine if your edible oils are rancid
Rancidity is the process through which oils and fats become partially or completely oxidized after exposure to moisture, air, or even light. Though not always that obvious, foods can go rancid long before they become old. For oils, whose antioxidant properties are...
