Explore how Raman spectroscopy supports quantitative pharmaceutical analysis by enabling accurate measurement of active ...

Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...

Laser lights are usually employed for the Raman spectroscopic analysis. The photons emitted by the laser light are absorbed by the sample, temporarily entering a non-stationary, exceedingly brief ...

A novel method detects hydrogen at extremely low concentrations by enhancing molecular signals, enabling accurate monitoring, and advancing safety in hydrogen-based energy systems.

A research team led by Prof. Fang Yonghua from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences proposed and systematically optimized a novel parabolic mirror ...

During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...

RIKEN researchers have demonstrated a method that can detect tiny amounts of biomarkers in liquid samples and can distinguish ...

This article discusses the identification of polymers such as ABS, PE, PS, PET, and PMMA in various dyes using Raman spectroscopy. Rapid and non-destructive identification is achieved once a suitable ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...
