![]() ![]() Without additional manipulation, the assay can be conducted on heterogeneous solutions with significant degree of turbidity, such as the presence of suspensions or aluminum-containing adjuvants. The relatively small sample requirements and amenability for automation make this assay an attractive tool for detecting residual H(2)O(2) levels. ![]() This method was found to be highly robust and reproducible, with a level of detection of 0.015 ppm and a level of quantitation of 0.025 ppm (in water). A sensitive and convenient microplate-based method with fluorescence detection for H(2)O(2) quantitation was recently reported (Towne et al., 2004, Anal Biochem 334: 290-296). Quantitation of residual hydrogen peroxide (H(2)O(2)) and evaluation of the impact on product stability is necessary as unwanted H(2)O(2) can potentially be introduced during the manufacturing of pharmaceuticals, biologics, and vaccines. ![]()
