Soil quality - Pretreatment of samples by freeze-drying for subsequent analysis (ISO 16720:2005)

ISO 16720:2005 specifies a method for pretreatment of soil samples by freeze-drying for subsequent analysis.
ISO 16720:2005 is applicable to soil samples for subsequent determination of elements or organic compounds recognized as non-volatile under freeze-drying conditions. Generally, ISO 16720:2005 can also be applied to samples from sludges and sediments.
This method is also applicable as a first step for the determination of dry matter (or water) content, for instance in the case of samples with high water content.

Bodenbeschaffenheit - Vorbehandlung von Proben durch Gefriertrocknung für die anschließende Analyse (ISO 16720:2005)

Diese Internationale Norm legt ein Verfahren zur Vorbehandlung von Proben durch Gefriertrocknung für die anschließende Analyse fest.
Diese Internationale Norm ist für Proben aus Böden für die anschließende Bestimmung von Elementen oder organischen Verbindungen anwendbar, die unter den Bedingungen der Gefriertrocknung als nicht-flüchtig identifiziert werden. Grundsätzlich kann diese Internationale Norm auch für Schlamm- und Sedimentproben angewendet werden.
Die Gefriertrocknung kann als erster Schritt bei der Bestimmung des Trockenmasseanteiles (oder des Wassergehaltes) angewendet werden, beispielsweise im Falle von Proben mit einem hohen Wassergehalt.

Qualité du sol - Prétraitement des échantillons par lyophilisation pour analyse subséquente (ISO 16720:2005)

L'ISO 16720:2005 spécifie une méthode de prétraitement par lyophilisation d'échantillons destinés à être soumis à une analyse ultérieure.
L'ISO 16720:2005 est applicable à des échantillons de sols qui vont être ensuite soumis à un dosage d'éléments ou de composés organiques reconnus comme étant non volatils dans les conditions de lyophilisation. D'une façon générale, l'ISO 16720:2005 peut aussi être applicable à des échantillons de boues et de sédiments.
Cette méthode peut aussi être utilisée en tant que première étape pour déterminer la teneur en matière sèche (ou en eau), par exemple dans le cas d'échantillons ayant une teneur en eau élevée.
