title: [Analysis of nitrate and nitrite in feed. 2. Potentiometric nitrate determination with ion sensitive electrodes].
abstract: Nitrate-sensitive PVC matrix membrane electrodes produced in the German Democratic Republic are suited for determining nitrates in feeds and plants if the different causative parameters are taken into account. A rational determining method is presented. Comparisons with the o-cresol method showed statistically confirmed agreement.
