ABSTRACT:
A method for measuring NO.sub.x in biochemical processes which includes a) isolating a liquid sample; b) adjusting the pH or ionic strength of the sample; c) recording mV values present in the sample after predetermined time periods; d) determining NO.sub.x concentrations in the sample at each of the predetermined time periods from the mV values; e) determining the difference in NO.sub.x in the sample from the NO.sub.x concentrations at each of the predetermined time periods; and f) determining the NO.sub.x concentration of the liquid sample from the difference in NO.sub.x and the predetermined time periods.
