The N-H stretching and bending peaks can be used to distinguish primary, secondary, and tertiary amides and to ascertain protein structure. Here’s how.

An important class of nanoparticles made of “upconversion” materials has found a central role in sensing. These nanoparticles are used to convert longer-wavelength photons into shorter-wavelength fluorescence to detect temperature, pH, gas molecules, ions, and trace biomolecules.

The U.S. and European Pharmacopeia chapters covering ultraviolet and visible spectroscopy have recently undergone significant revision, leading to important differences between them. We explain how those changes affect the steps you need to take to qualify your instruments.

This slender volume belongs on the bookshelf of every experimental spectroscopist, and offers an alternative to a large, comprehensive textbook for an undergraduate instrumental chemistry course.

This study shows, for the first time, that limits of detection (LOD) can be improved for P, S and Ca nanoparticles by the addition of N2 to the plasma flow for single-particle inductively coupled plasma–mass spectrometry (spICP-MS). The work also examined the relative LOD differences using Ar-N2 and Ar-N2-H2 mixed-gas plasmas.
