Chemical analyses for the detection of reactive oxygen and nitrogen species (RONS) in PAW. (a) Undiluted PAW (blue) generated by exposing deionized H₂O to cold plasma for 5 min at 900 W torch #1 power was analysed by ion chromatography. Deionized H₂O (grey) was used as a control. NO₂⁻ (pink) and NO₃⁻ (purple) solutions were used as standards. Representative traces are shown. (b) Determination of H₂O₂ (green), NO₂⁻ (yellow), and NO₃⁻ (red) concentrations in PAW generated in six different batches.
