New Application Note on the ASTM D5799 alternative for the trace analysis of Peroxides in 1,3-Butadiene
To eliminate any safety hazard and to provide accurate results Da Vinci Laboratory Solutions has introduced the Fast Peroxide Analyzer (FPA) based upon a flow injection system. The FPA system uses an Agilent 1260 Infinity II HPLC system configured with a pump, an autosampler, a DVLS reaction module and a variable wavelength detector. A Pressure Station is used for the safe handling of liquid Butadiene.
The latest application note shows the analysis results of a Pentane standard and two 1,3-Butadiene samples. Both Butadiene samples are analyzed in tenfold to measure the repeatability.
The analysis results exhibit that the iodometric titration method D5799 suffers from poor repeatability and reproducibility for the intended range. The FPA analysis results demonstrate that the DVLS Fast Peroxide Analyzer greatly improves the repeatability and reproducibility compared to the ASTM D5799 method. As it also significantly reduces the analysis time, the DVLS Fast Peroxide Analyzer is a safe, fast and accurate alternative for the analysis of Peroxide traces in 1,3-Butadiene.
