Short summary

In this study, a calibration device for OH and HO₂ instruments is characterized at pressures of 275 to 1000 mbar, allowing instrument pressure sensitivity to be quantified to an accuracy of 22 % (1σ). Computational fluid dynamic simulations supporting the understanding of interactions between generated HO_x and the instrument inlet led to enhanced determination of factors affecting instrument sensitivity.
