This white paper discusses the possibilities of rapid, point-of-care virus testing using inexpensive and easy-to-use screen-printed electrodes that are produced with ISO 13485 certification ("Manufacturing of sensors for medical devices"). Compared ...
Metrohm is pleased to present an Application Bulletin describing the determination of free and total chlorine by iodometric titration. To disinfect water for human consumption, chlorine is added to the water in some countries. Because ...
BSK Labs runs a number of environmental laboratories and service centers along the west coast of the US. A total of 70 employees – including microbiologists, chemists, lab technicians, and support staff – make sure that the 200 to 350 ...
Carcinogenic or not? The broad-spectrum herbicide glyphosate is used all over the world in agriculture. Alongside farming, the chemical is also used for weed-killing in domestic gardens and in public and private spaces kept free from «vegetal ...

The pH value is one of the most important and therefore also one of the most frequently measured quantities in analytical chemistry. Sometimes, a simple pH test strip is sufficient for making a rapid check; precise pH meters are, however, required ...
Thanks to growing environmental awareness, waste is increasingly being separated and recycled. However, residual waste always remains that can`t easily be recycled. This ends up in waste incineration plants (referred to as KVAs in Swiss German) for ...
Atmosperic aerosols have a strong impact on the climate. Within the organic aerosol fraction, anhydrosugars and sugar alcohols are valuable tracers for biomass burning and biogenic sources. They are best determined by ion chromatography coupled to ...
Ion chromatography (IC) with conductivity detection has been successfully used to analyze low-molecular organic compounds such as amines and organic acids, as well as anionic and cationic substances. However, due to current toxicity concerns and the ...
Current US and European standards stipulate gas chromatography to determine the glycerol content in biodiesel. However, this method is both tedious and rather expensive. Metrohm recommends ion chromatography (IC) as a simple, cost-efficient and ...
A complete tap water analysis includes the determination of the pH value, the alkalinity and the total water hardness. Both the pH measurement and the pH titration by means of a standard pH electrode suffer from several drawbacks. First, the ...
