To monitor the traces of reactive peroxides Da Vinci Laboratory Solutions has developed the Fast Peroxide Analyzer. The analyzer is based on an HPLC stack including a quaternary pump, an automated sample introduction system, an UV detector and instrument control processing software.
The DVLS Fast Peroxide Analyzer (FPA) is based on an HPLC stack including a quaternary pump, an automated sample introduction system, an UV detector and instrument control processing software. The analysis of Peroxide, as active Oxygen, is based on the oxidation of Iodide by Peroxide:
ROOH + 2I- + 2H → ROH + I2 + H2O
Two reagents: Acetic Acid in Propanol and Sodium Iodide in Propanol are mixed, resulting in a stream of acidified Iodine solution in Propanol. The sample is injected into this stream. Iodine is formed under temperature controlled conditions inside a dedicated reaction ovenmodule developed by Da Vinci. The HPLC UV detector spectrophotometrically determines the formed Iodine, which is proportional to the level of peroxide. The instrument software not only controls the optimal instrument conditions, but also automates the data analysis and reporting. The required analysis time is 7 minutes.
The Fast Peroxide Analyzer is based on a customized method as an alternative to:
The FPA determines both hydrogen peroxides & organic peroxides in:
Safe alternative to traditional wet chemistry analysis methods such as ASTM D2340 en ASTM E299
Standard HPLC modules contribute to a precise determination of Peroxide
Fast analysis of only 7 minutes
Modular design saves benchspace
