An on-line nitric oxide (NO) monitoring method is described employing a flow injection manifold with chemiluminescence (CL) detection. The method is tailored for monitoring the NO from its complexes with porphyrin ring-bearing (PRB) biochemical materials. The method is optimized for sensitivity and detection limit. The method is quite sensitive, simple, rapid, and precise. A sensitivity of 2.63 x 10(5) mV mol(-1) NO, a range of 2.0 x 10(-5) up to 1.0 x 10(-2) mol NO (under the conditions used) a reproducibility of 1.0% over the range 1.0 x 10(-3) up to 1.0 x 10-2 mol NO, a frequency of ca. five samples per minute and a detection limit of 1.0 x 10(-5) mol NO are the analytical figures of merit for the proposed method.
