(Main)Water quality - Spectrophotometric determination of chlorophyll-a content by ethanol extraction for the routine monitoring of water quality
Water quality - Spectrophotometric determination of chlorophyll-a content by ethanol extraction for the routine monitoring of water quality
This document specifies a spectrophotometric method for determining the chlorophyll-a content as a measure of the amount of phytoplankton in surface water. Assuming a maximum sample volume of 2 l, chlorophyll-a content of 5 μg/l or more can be determined.
Wasserbeschaffenheit - Spektrophotometrische Bestimmung des Chlorophyll-a-Gehalts durch Ethanolextraktion für das Routinemonitoring der Wasserqualität
Dieses Dokument legt ein spektrophotometrisches Verfahren zur Bestimmung des Chlorophyll a-Gehalts als Maß für die Menge an Phytoplankton für alle Arten von Wasser fest. Bei einem angenommenen größten Probenvolumen von 2 l können Chlorophyll a-Gehalte von 5 µg/l oder mehr bestimmt werden. Die Bestimmungsgrenze kann von jedem Labor individuell berechnet werden und kann bis zu 0,5 µg/l bei Verwendung einer Probe von 2 l (oder mehr) und einer 50 mm-Küvette betragen.
Qualité de l'eau - Détermination spectrophotométrique de la teneur en chlorophylle a par extraction à l'éthanol pour la surveillance de routine de la qualité de l'eau
Le présent document décrit une méthode spectrophotométrique pour déterminer la teneur en chlorophylle a comme mesure de la quantité de phytoplancton dans tous les types d’eaux. En supposant que le volume d'échantillon maximal est de 2 l, des valeurs de teneur en chlorophylle a de 5 µg/l ou plus peuvent être déterminées. La limite de détermination peut être calculée par chaque laboratoire individuellement et peut atteindre 0,5 µg/l en utilisant 2 l d’échantillon (voire plus) et une cuve de 50 mm.
