Moisture anomaly in analysis of peroxyacetyl nitrate (PAN)

Preliminary data using gas chromatography with an electron capture detector to measure PAN indicate particular anomalies when calibrating and measuring low ppb PAN levels. At constant concentrations of PAN, but with changing humidities, a definite instrument response change is observed. Humidities b...

Zusammenfassung:	Preliminary data using gas chromatography with an electron capture detector to measure PAN indicate particular anomalies when calibrating and measuring low ppb PAN levels. At constant concentrations of PAN, but with changing humidities, a definite instrument response change is observed. Humidities below 30% result in much lower response values.
