Efecto de la salinidad Arjonilla, M Blasco, J ammonium nitrites phosphates silicates salinity autoanalyzer amonio nitritos fosfatos silicatos salinidad autoanalizador The continous flow autoanalyzer is an instrument commonly used for nutrient analysis in coastal laboratories and oceanographic vessels. The determination of micronutrient concentrations (ammonium, nitrites, nitrates, silicates and phosphates) makes it necessary to evaluate precisely how variables can affect this measure. In this sense, salinity is a parameter which must be considered, due to its wide range of variation (0–36) in estuarine ecosystems. In this work, the effect of salinity on nutrient (ammonium, nitrites, silicates and phosphates) determination is analyzed. The results show that salinity does not affect the measure of nitrites and phosphates, whereas ammonium and silicates are affected. Practical considerations of nutrient measurement with samples of different salinities are pointed out. Los equipos automatizados de flujo continuo son instrumentos frecuentes en el análisis de nutrientes en laboratorios costeros y en buques oceanográficos. La determinación de la concentración de los micronutrientes (amonio, nitritos, nitratos, silicatos y fosfatos) requiere la evaluación precisa de aquellas variables que pueden que afectar a su medida. En este sentido, la salinidad es un parámetro que es necesario considerar, habida cuenta del amplio intervalo de variación que puede presentar en ecosistemas estuáricos, entre 0 y 36. En este trabajo se analiza el efecto de este parámetro en la determinación de los nutrientes: amonio, nitritos, fosfatos y silicatos. Los resultados analizados ponen de manifiesto que este parámetro no afecta a la medida de nitritos y fosfatos, mientras que sí lo hace para el amonio y silicato. Se señalan también aplicaciones prácticas a la medida de nutrientes en muestras en un amplio intervalo de salinidad.
