Monitor Thresholds Reliably: Reflectoquant® Peroxide Test

When you open a bottle of loose tablets, you often find a cotton ball under the lid. This filling material protects the pills from damage during transportation. Many pharmaceutical companies use hydrogen peroxide to sanitize these cotton balls. The USP (United States Pharmacopoeia) has now defined thresholds for hydrogen peroxide residues in cotton which is used as a packaging component with pharmaceuticals. The USP recommends the Reflectoquant® peroxide test for reliable in-process monitoring.

Reflectoquant® Peroxide Test Available For Two Measuring Ranges

The USP 670 draft states that, in the future, no more than 50 ppm of peroxide will be permissible per gram of cotton fiber: Before measuring, the fibers must be stirred for three minutes in 30 ml distilled water.

 Merck offers the Reflectoquant® peroxide test for two measuring ranges:

The test for the lower measuring range (116974.0001) is the one which is recommended by the USP for the application described.
