Researchers have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of the light by ...

A gap-controlled infrared technique makes it possible to study molecular interfaces with high sensitivity using affordable, widely available lab equipment. These molecular interfaces are everywhere—on ...

Using the shrink-assembled liquid 3D hot spot matrix as a microreactor, a new method for quantitative detection of blood drug concentration by surface-enhanced Raman spectroscopy (SERS) was ...

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...

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 ...

Laser spectroscopy has enabled non-invasive chemical analysis of Darwin’s preserved specimens, improving long-term museum ...

Dynamics Author: Howard Goldner During the past few decades, fluorescence spectroscopy has developed into an integral technique in many scientific disciplines. In the life sciences, it is implemented ...

Freeform dual comb spectroscopy creates images of methane plumes not visible to the human eye. Dual comb advance: Esther Baumann works in the lab at NIST. Scientists at the U.S. National Institute of ...

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 ...

Microplastic (MP) pollution poses a major concern, especially in aquatic environments, necessitating efficient detection technologies to safeguard marine life as well as human health. However, ...
