Abstract
Measurements of ultra-low CO oxidation rates of materials suitable for construction of a hydroxyl radical monitor are described. The procedure consists of passing an ultrapure
14CO tracer over the test material and collecting the resultant
14CO
2. Oxidation rates are measured for stainless steel, aluminum, alumina, titanium, and Teflon. Results show the oxidation rate with aluminum is at least an order of magnitude less than any other material (<10
4 cm
−2s
−1). These rates are three to four orders of magnitude lower than reported previously in the literature. Application to a ground-based hydroxyl monitor is discussed.
