Rapid, convenient analysis of regulatory sum parameters in effluent, river water and ground water is facilitated by the newly developed, second generation mainframe of the legendary NIPHO® On-line Total Nitrogen+Phosphorus Analyzer. At first glance the NIPHO® shares the typical look familiar of the range of water analyzers of AppliTek’s On-line Analyzer Suite. Underneath this, the analyzer harnesses a mainframe especially developed for the simultaneous, automatic measurement of Total N and P in water.
Traditionally, compliance of waste water effluent with local discharge regulations is assessed by a number of well-known nutrient parameters, such as nitrate and soluble phosphate concentrations. However, the dynamic nature of nitrogen speciation and phosphorus fractions in treated waste waters and natural waters cannot be underestimated as it may contribute significantly to the total nutrient load of the water body.
The use of AppliTek’s proprietary oxidation technique is key to converting all N and P species into nitrate and orthophosphate. Contrary to the traditional design of AppliTek’s colorimeters, however, the NIPHO® employs a very compact spectrometer for the measurement of the absorbance of phosphate and nitrate at 630 nm and 220 nm respectively. The new spectrometer combines high thermal stability with low drift, and excellent signal-to-noise ratio.
