Data and protocols for the publication: "Harmonizing measurements of oxidative potential of PM: an interlaboratory comparison of the ascorbic acid assay"

This repository contains: the simplified protocols for measuring oxidative potential of PM with the AA assay, adapted for cuvettes and plate-readers (with and without automatic injectors) the Excel file for OP-AA data treatment distributed to the participants of the study / Note that sheet protection can be removed (no password) the aggregated results for the simplified and individual "home" protocols This material is supporting the results presented in the manuscript: "Harmonizing measurements of oxidative potential of PM: an interlaboratory comparison of the ascorbic acid assay" in Atmospheric Measurement Techniques (2026).
