A peroxidase‐based biosensor, coupled to a newly designed remote probe, is used for monitoring peroxide species at large sample‐instrument distances. The new bioprobe can operate over a broad pH and ionic‐strength ranges relevant to natural water conditions. Measurements of micromolar levels of hydrogen peroxide and 2‐hutanone peroxide in untreated river and groundwater samples are demonstrated, and prospects and challenges for remote field applications are discussed.
