The FIAstar 5000 system is for automatic wet chemical analysis of nutrients and other parameters in groundwater, wastewater, soils, plants, fertilizers, wine, and food. The system's fast flow injection technology performs analysis in less than 1 minute while its Digital Dual Wavelength detector assures increased accuracy and improved lower detection limits by canceling the effects of air bubbles and background changes in the carrier solution. Up to three separate analyses can be performed simultaneously and an optional auto-sampler allows up to 120 samples to be preprogrammed for fully automatic analysis.
