Abstract
Water samples with specific conductances ranging from 66 to 6950 ??mho/cm at 25 ??C were analyzed for ammonia-N (NH3-N), nitrate plus nitrite-N (NO3 + NO2-N), nitrite-N (NO2-N), and phosphate-P (PO4-P) by using both a "segmented-flow" analyzer and a "discrete" analyzer. Plots of the discrete vs. the segmented-flow results showed linear correlation coefficients of 0.9980 for NH3-N, 0.9997 for NO3 + NO2-N, 0.9998 for NO2-N, and 0.9950 for PO4-P. The significances of the slope and the y intercept of each plot are discussed in terms of possible biases which may exist between the two systems. Data concerning precision and accuracy for both analyzers are presented. For the four analytes, the rate of sample analysis was 60 samples per hour on the discrete analyzer and 40 samples per hour on the segmented-flow analyzer. ?? 1981 American Chemical Society.
