Microplastics are becoming a major global environmental concern
The different steps involved in getting from the raw sample to answers—including the initial sampling through to data analysis—are discussed in this article.
Spectroscopy Applications
The analysis of elemental content is critical to ensuring the quality and safety of drinking water. Regulations such as Directive (EU) 2020/2184 and ISO 17294 provides guidelines for using ICP-MS for water analysis, aiming to protect human health from the adverse effects of its contamination.
This Application Note demonstrates the analysis of chlorine (Cl) in oil according to ASTM D4929 except that a rhodium anode tube has been used.
This note presents a reinvestigation and revaluation of the quantum yield of 2AMP in 1 M H2SO4 using quinine bisulphate in 1 M H2SO4 as the reference standard with a modern spectrofluorometer.
Detailed analysis of the temperature-induced changes in the spectra can be used to obtain insights into the phase behaviour of mixtures such as the soaps described in this application.
This note looks at design options to optimise sensitivity, size and wavelength and how they can stretch the limits of applied Raman spectroscopy.
