Sickles et al. (1990) compare methods for sampling and
analysis of atmosphe~:ic constituents that are important contributors
to acidic dry deposition, and they monitor NO2
with continuous luminol-based chemiluminescence monitors.
Two instrumenl:s were used in the current study. One
employs a temperatrLre-controlled (30°C) reaction cell, and
another uses electronic signal processing to compensate for
temperature fluctuations.
