The kINPen-sci was operated at a sinusoidal waveform of 860 kHz with a peak-to-peak voltage of 3kV. The COST-Jet was operated at a sinusoidal waveform of 13.56 MHz with a peak-to-peak voltage of 850 V.

\n", "procedure": "

The symmetry axis of the plasma effluent is defined as the z-axis. For both plasma jets, this position is normalised to the tip of the respective jet\u2019s nozzle, such that the effluent exits the source at z = 0.

Humidified helium containing (3300 +- 100) ppm water at a flow rate of 1 slm at atmospheric pressure.

Spatially resolved measurements of H2O2 number densities in the effluent of both plasma jets:
\nThe optical cavity is composed of two highly reflective mirrors (Lohnstar Optics, reflectivity 99.98%, radius of curvature 100 cm), separated by a distance of 54.5 cm. The first cavity mirror holder was connected to a to a piezoelectric ring actuator (RA12-24, Piezosystem Jena) and a function generator (AFG 3000 C, Tektronix), so that the cavity length is continuously modulated by 4 \u03bcm.
\nA quantum cascade laser (QCL) with a tuning range of 1224 - 1234 cm\u22121 (HHL-223, Alpes Lasers) was used. The laser control unit comprised a low-noise QCL driver (QCL1000, Wavelength Electronics) and temperature controller (PTC5K-CH,Wavelength Electronics).

\n", "procedure": "

The absorption feature of the optical transitions in the \u03bd6 band of H2O2 was probed within the spectral range of 1231.57 - 1232.00 cm\u22121, in order to determine the line-of-sight integrated H2O2 density and the pressure broadening coefficient from a model fit. Under the assumption that the effluent, and therefore the distribution of H2O2, is rotationally symmetric, an Abel inversion yields the spatially resolved density distribution of H2O2 in the effluent of both plasma sources.
