I will repeat here what I have already stated: There is no test strip that can detect peroxides in the air above a liquid flask. Methodologically it is simply unavailable (and I state this as a professional).
ETD of swabs on the outside of a flask could detect peroxides, but not test strips waved in the air. That is pure security theater.
