Video demonstrates a Safe and Fast analysis of Peroxide traces

Determining the Peroxide content is an essential aspect of petrochemical processing as Peroxides may impact product quality and present a serious safety hazard. An innovative solution to detecting Peroxide traces is the Fast Peroxide Analyser developed by Da Vinci Laboratory Solutions (DVLS). In a product video the system configuration of the Fast Peroxide Analyser is explained followed by a demonstration of the analysis of Peroxide traces in petrochemical streams.

Peroxide Analysis Method

The setup of the Fast Peroxide Analyser (FPA) is based on Agilent HPLC hardware configured with a Reaction Module, AutoSampler or Sampling Valve and a Variable Wavelength Detector. The Pressure Station allows safe handling of the pressurised liquefied gas sample contained in a cylinder. The sample is injected into the reagent stream of acidified Iodide and transferred to the Reaction Module. The Peroxides present in the sample react with Iodide to form Iodine. The DVLS Reaction Module is designed to optimise the conversion to Iodine. The yellow-brownish color of Iodine is measured by the UV-VIS detector. The Agilent OpenLab software is used to start the analysis. In less than 5 minutes the Peroxide content is determined. The analysis results demonstrate an excellent performance down to ppb level.

Various Applications

Several applications notes describe the use of the FPA system. One important application is the analysis of Peroxides in 1,3-Butadiene. In the Butadiene application note the FPA analysis is compared with ASTM D5799 method for the analysis of Peroxide Traces in 1,3-Butadiene. Two Butadiene samples are analysed in tenfold to measure the repeatability. The DVLS FPA analysis results demonstrate that the FPA greatly improves the repeatability and estimated reproducibility. It also significantly reduces the analysis time.
