METHOD OF MEASURING NO IN LIQUIDS Russian patent published in 2004 - IPC

FIELD: analytical methods. SUBSTANCE: method comprises isolation of liquid sample, adjusting pH and/or ionic force of sample for time NO_x, registering mV value using t₀-selective probe at predetermined time NO_x, and registering one more value t₁ after one more predetermined time mV₂, after which concentration of t₂ in sample is determined for each predetermined time interval NO_x and t₁, determining change in t₂, and then concentration of NO_x. EFFECT: simplified procedure and expanded application possibilities. 3 cl, 3 dwg
