Spectrophotometric Determination of Potassium Bromate Concentration in Bread via Redox Reaction With Promethazine in Acidic Conditions
Potassium bromate as an oxidizing agent in bread production is a staple, but it also poses health risks due to its classification as a carcinogen, necessitating careful monitoring of its residual levels. This application note reviews the spectrophotometric determination of potassium bromate concentration in bread based on the redox reaction between potassium bromate and promethazine in an acidic environment.
Poster Presentation - RISE imaging of various phases of SiC in sintered silicon-carbide ceramics
November 12th 2024In this poster presentation applications manager Ute Schmidt discusses the use of correlative Raman-SEM (RISE Microscopy) imaging for analyzing silicon-carbide (SiC) ceramics. The main focus of the work is investigating the distribution of sub-micron structured polytypes of SiC grains on and below the surface.
FT-IR gas analysis of coal-to-ethylene glycol process
October 31st 2024Coal-to-ethylene glycol is the process by which ethylene glycol is synthesized from coal instead of traditional methods using petroleum as the raw material. This study demonstrates that Fourier Transform Infrared Spectroscopy (FT-IR) can be a reliable alternative to simultaneously measure methyl nitrite and other process gases (such as CO and NO) using a single ABB analyzer.
