Title (EN) IN-SITU MEASUREMENT OF NITRATE IN SOIL
(FR) MESURE IN SITU DE NITRATE DANS LE SOL
Abstract:
(EN) A system for measuring with the aid of light absorption spectrometry the concentration of one or more analytes in porewater in soil, the system comprising: one or more monitoring unit(s), each monitoring unit comprising a porewater sampler (1), an optical flow cell (2) with a tube connecting the liquid inlet port of said optical flow cell to said porewater sampler; and vacuum arrangement to enable extraction of porewater; at least one light source (5) for generating a light beam to be transmitted through said optical flow cell (2); and at least one detector (8) for obtaining spectral information from the beam exiting said optical flow cell. A method of measurement is also provided.
(FR) L'invention concerne un système de mesure, par spectrométrie d'absorption de lumière, de la concentration d'un ou de plusieurs analytes dans de l'eau interstitielle dans le sol, le système comprenant : une ou plusieurs unités de surveillance, chaque unité de surveillance comprenant un échantillonneur d'eau interstitielle (1), une cellule de flux optique (2) avec un tube reliant l'orifice d'entrée de liquide de ladite cellule de flux optique audit échantillonneur d'eau interstitielle ; et un agencement de vide pour permettre l'extraction de l'eau interstitielle ; au moins une source de lumière (5) pour générer un faisceau lumineux à transmettre à travers ladite cellule de flux optique (2) ; et au moins un détecteur (8) pour obtenir des informations spectrales à partir du faisceau sortant de ladite cellule de flux optique. Un procédé de mesure est également décrit.
