Determination of Iron(II), Iron(III), total and free acid in an etching bath

Acid etching baths are used for oxide removal and cleaning of the surface of different types of steel. To keep the bath in an optimum condition the Fe2+/Fe3+ and free acid/total acid ratios must be maintained within certain limits. Auxiliary substances like hydrogen peroxide are added to influence the Fe2+/Fe3+...

Analysis of Bayer aluminate liquors

Aluminium is used everywhere: in automobiles, bicycles, soft drink cans, cookware, and is even found in most antiperspirants, yet it does not occur in a natural state. Aluminium is a reactive base metal, and is mainly refined from bauxite ore, which contains approximately 60% alumina (Al2O3). To smelt aluminium directly...

Mercaptans and hydrogen sulfide derived from crude oil according to ASTM D3227 and UOP163

Mercaptans (thiols) and hydrogen sulfide (H2S) Fossil fuels are known for their sulfur content, which originates from the decomposition of dead organisms over millennia. Mercaptans (thiols) and hydrogen sulfide (H2S) are two sulfur compounds present in crude oil which contribute to its characteristic odor. In the refining process, these can...

Sustainable water management in breweries – alkalinity and hardness testing

More and more breweries are taking steps to become more sustainable regarding their water usage, which means process optimisation and more efficient practices. To this end, process parameters of the used water such as alkalinity, hardness and pH value have to be determined. Alkalinity in water is due to the...

MORE EFFICIENT – new titration software puts the sample in the focus

Who can do titration in your lab? Everyone (with Metrohm’s brand-new OMNIS system). Before OMNIS, titration sometimes meant exposure to hazardous liquids. Not any longer: The patented OMNIS Liquid Adapter allows you to exchange reagents without opening a single bottle! Learn more! -> Learn how OMNIS makes titration MORE EFFICIENT!...

Ammonia in wastewater – Request a sample SAT report

The most robust way to measure ammonia concentration is to use a colorimetric measurement. Depending of the sample matrix various preparations can be automated. Normally samples are filtered and diluted in prior of measurement. Our ammonia analyser is designed to operate with very minimal manual work and running cost. It...
