A new Raman spectrometer combines non-destructive analysis, automated sampling and flexible lasers to enable faster at-line quality control.

The biopharmaceutical sector is transitioning from reactive off-line quality control to a proactive quality by design (QbD) framework. Process analytical technology (PAT) enables this shift through ...

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 ...

Precise natural gas measurements are critical in any environment. This article demonstrates how Raman spectroscopy and chemometric modeling can offer accurate natural gas measurements in any situation ...

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 ...

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 ...

There are around 20 known MXene structures at present, and some of the main excitement around these materials comes from some of their potential applications, including as energy storage materials. 2 ...

Optical photothermal infrared (O-PTIR) spectroscopy is an infrared super-resolution measurement technique where a shorter ...

Graphene is a material that has a one-atom layer of carbon atoms with a thickness of only 335 pm. It can be modified using oxidization and functionalization. For example, graphene gains properties ...
