What is Quantum Yield?
The IUPAC definition of quantum yield (Φ) is the number of a certain event occurring per photon absorbed by the system.1However, it is most commonly written specifically for the emission of light (photoluminescence) by a system2-5 This narrower definition is often simply called quantum yield; with the emission of light being implicit given the context. However, the terms fluorescence, ...

Atmospheric Microplastic Collector System
The Atmospheric Microplastic Collector has been developed to collect microplastics in deposition, minimizing contamination risks. Innovation nilu’s Atmospheric Microplastic Collector collects representative samples of dry and wet atmospheric particulate fallout for subsequent analysis. The collector is made from stainless steel to avoid contamination from the sampler.

How to Manage Challenges in Analysis of Highly-Viscous or Inhomogeneous Organic Liquids
Organic materials are the most challenging sample matrices for element analysis techniques, such as ICP-OES and -MS, AAS, and combustion based elemental analysis techniques for determination metals and non-metal elements like sulfur, nitrogen and chlorine. One reason is the wide concentration range, from a few ppt in applications (like silicone or chlorine in naphtha) to weight percentage in ...
