Green hydrogen generation: A cross-disciplinary challenge rooted in electrochemistry
Green hydrogen, produced from water electrolysis using renewable energy sources, is being explored as a strategy to reduce the dependence on fossil fuels and decarbonize chemical processes. From an environmental standpoint, this approach is extremely attractive given...
NIR spectroscopy in the petrochemical and refinery industry: The ASTM compliant tool for QC and product screening – Part 3
What is Pyrolysis gasoline or «Pygas»? Pyrolysis gasoline, also known as Pygas, is a byproduct of naphtha cracking during the production of ethylene and propylene. Pyrolysis gasoline is an easily flammable, colorless liquid with high aromatic contents and...
Guide to online and inline surface finishing analysis
What is surface finishing? Surface finishing is a series of industrial processes with the main goal to alter the surface of a certain workpiece in order to obtain specific properties. This can be performed chemically, mechanically, or even electronically with the aim...
The evolution of handheld 785 nm Raman spectroscopy: Raman extraction from fluorescence interference
MIRA DS (Metrohm Instant Raman Analyzer) is a handheld Raman system that identifies materials using 785 nm laser excitation. The advantages of using 785 nm Raman are well understood. Excitation with shorter wavelengths produces strong Raman scattering with short...
Cyclic voltammetry (CV) – the essential analytical technique for catalyst research
Cyclic voltammetry (CV) is the backbone of most electrochemical research and is an essential electrochemical technique that allows researchers to explore candidate catalysts in greater depth. When coupled with modeling, a systematic goal-focused protocol will supply a...
Best practice for separation columns in ion chromatography (IC) – Part 2
The second part of this blog series about best practice for IC separation columns focuses on application related topics that have an impact on the column suitability and stability. First, there is the proper choice of the column that best suits the intended...
Best practice for electrodes in Karl Fischer titration
Have you ever asked yourself why you need an electrode for the endpoint detection in Karl Fischer (KF) titration? Theoretically, the endpoint of a Karl Fischer titration could be determined based on the color change of the reagent. However, if accuracy and...
NIR spectroscopy in the petrochemical and refinery industry: The ASTM compliant tool for QC and product screening – Part 2
Differences between gasoline, diesel, and jet fuel Gasoline is a fuel made from crude oil and other petroleum-based liquids, containing carbon numbers generally between 4 and 12, and exhibiting boiling points of up to 120 °C. Gasoline is primarily used as a fuel...
Staircase or linear scans: two options for reliable electrochemical experiments
Electrochemical experiments are performed by delivering and controlling a potential or current signal to the electrochemical cell/device under test and measuring its response through a potentiostat/galvanostat (PGSTAT). Here, two different options for performing...
Coffee: serving up chemistry in every cup
International Coffee Day is October 1st, not that many of us need a day to celebrate the drink we enjoy all year round. What makes a high quality cup of coffee? There are several factors at hand from the origin of the beans and the climate they grow in, to how the...
