Conservación de muestras de agua de mar para la determinación de nitrógeno orgánico

Abstract

[EN] Chloroform, benzene and mercurie acetate were used as preservative chemicals in sea water samples for total and dissolved organic nitrogen determinations. Chloroform resulted the most efficient chemical. It was efficient for preservation of filtered samples for one hundred days. None of these preservatives was efficient in unfiltered samples. Even using chloroform, losses are appreciated after twenty days

[ES] La determinación de nitrógeno orgánico es preferible hacerla siempre a las pocas horas de recogida la muestra para evitar cambios en su contenido, pero esto sólo es posible cuando las muestras son de agua costera próxims al laboratorio. En cruceros oceanográficos no es posible hacer las determinaciones a bordo porque se necesita una limpieza extrema si se quiere obtener números corectos. [...]
