The effects of different storage procedures on the analysis of nitrate, phosphate and silicate in seawater samples have been compared. The storage procedures included freezing and refrigeration of seawater samples, the latter with and without the addition of chloroform as a preservative. Refrigeration of the samples (1-3°C) up to 6 days, without preservative, was found to be the most reliable storage procedure. For periods longer than 6 days, addition of chloroform (0.5-1% v/v) will preserve the samples for months without significant losses in accuracy and precision.
