Intercalibration of peroxyacetyl nitrate (PAN) liquid standards
Peroxyacetyl nitrate (PAN) solutions in the concentration range 10 ug to 100 ug PAN/ml solvent were successfully distributed and analyzed by 10 laboratories spread throughout Europe. Overall precision accounting for standards' preparation, air transport, storage and analysis resulted in standard deviations equal to 16 plus or minus 8% of the groups average for the high end, and 25 plus or minus 8% for the low end of the concentration range. Following the alkaline PAN hydrolysis, nitrite anions were determined by mostly chemically suppressed ion chromatography with better precision than the acetate anions whose determination was hampered with many error sources.
