The quantification of hydrogen peroxide can be challenging. Its small molecular structure and high oxidization strength make it very reactive. Many methods involved derivatization with some form of a chemical reaction. However, they are not always very reliable or reproducible. This talk will cover how to assay hydrogen peroxide directly, using High-Performance Anion Exchange chromatography with pulse amperometry detection (HPAE-PAD). There is no derivatization required. This method can be used for low-level analysis such as cleaning swabs and assaying the purity of hydrogen peroxide in the Semicon industry.
