Low Nutrient Seawater (LNS) can be used for the preparation of fresh standards and as a refractive-index blank.
Concentrated solutions of phosphate, nitrite, nitrate, silicate and ammonia are available for the preparation of working standards.
Calibration of analytical systems for nutrients in seawater requires standards to be prepared in seawater.
For the preparation of non-marine working standards, this kit contains concentrates of Nutrient Standard Solutions and de-ionised water for the preparation of fresh standards.
View our Seawater Standards Brochure for further details on all the standards available from OSIL.
