“…Results were within 0.1‰ relative to the initial value. A standard error of 0.1‰ was reported by Dudziak and Halas 29. Dudziak and Halas29 suggested also that their method could be used for soil air samples although they did not report the N 2 O concentration or the N 2 O/CO 2 ratio of the samples.…”

Dudziak and Halas29 suggested also that their method could be used for soil air samples although they did not report the N 2 O concentration or the N 2 O/CO 2 ratio of the samples. Drawbacks of this method are the inability to measure δ 18 O, the need for additional equipment, and a considerable prolonging of the analysis time.…”

“…The details of the experimental methods are described in our previous papers: (Halas and Dudziak, 1989;Dudziak and Halas, 1990). We used the linear dependence of the ion beam intensity upon the pressure of gas in the inlet system at low pressure range.…”
