.... However, Jperm becomes well-aligned for O2 between <10 and 50 ppb, so the impact does not differ significantly from experimental errors · At last, the presence of O2 in the test solution induced a test result that changed from FAIL to PASS for one grade but no impact on the other grade. Only 1 experiment...
