GAS FLOW INJECTION DETERMINATION OF NITROGEN DIOXIDE USING GALVANIC COULOMETRIC DETECTOR
摘要:
The direct determination of NO2 gas using a galvanic coulometric cell as detector by gas flow injection analysis (FIA) is described.The simple modification of the flow injection allows the linear range for the determination of NO2 gas from 0.01-2 ppm(v/v) to be expanded to 8-500 ppm(v/v) with a relative standard deviation of 3-4%(n=12) at a rate of 25 samples per hour and avoids the problem of time consuming in the equilibrium performance.
