Pythagoras first discovered that the vibrations of strings are drastically enhanced at certain frequencies. This discovery forms the basis of our tone system. Such natural vibrations ubiquitously ...

When two solutions of oppositely charged polymers (polyelectrolytes) are mixed, phase separation occurs and leads to the formation of a polymer-rich phase and a supernatant phase. The precise ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

Raman spectroscopy enables real-time bioreactor monitoring of glucose and lactate without breaching the sterile boundary.

Elemental spectroscopy is a method employed to examine in-service fluid samples such as engine oil or hydraulic fluid, to determine the presence and quantity of different substances. This approach ...

A medium-sized refinery lab can process 250 samples per day, whereas a big refinery can process up to 500 samples daily. Gas chromatographs, simulated distillation, flash and freeze point devices, ...
