DIN EN 16161:2012-09 EN 16161:2012 (E) 4 Introduction Surveys of chlorophyll and nutrient concentration are fundamental descriptors of primary productivity and eutrophic threat in coastal and inland waters. Chlorophyll-a concentration can be determined by sampling and laboratory a

35、nalysis using the techniques described in ISO 10260. Achieving consistent results with this technique requires careful attention during the various steps of the process commonly used, such as during sampling, transport, filtering, freezing, storage and extraction and subsequent pigment estimation. T

36、he in vivo technique described here can be applied to surveys where a rapid non-destructive and repeatable measurement capability is required. It can be used either in the field or laboratory. No chemicals are required. Utilised in association with other methods of chlorophyll-a determination such a

37、s ISO 10260, HPLC pigment analysis and chlorophyll fluorescence measurements techniques, it can help identify sources of inconsistency or be used as an alternative technique in its own right. As chlorophyll-a estimates can be achieved in times as short as one minute, the technique can enhance survey

38、ing capability considerably. This standard describes procedures to implement and verify performance.

47、 described 4 Principle The in vivo photometric absorption technique (IVP) is based on: a) the additive nature of absorption of individual constituents within a suspension; b) the use of a priori knowledge about the absorption features of chlorophyll-a in the wavelength area of approximately 675 nm;

48、c) the absence of other components interfering with spectral features of chlorophyll-a in this region; d) the use of a measurement cell (a cuvette or other sample receptacle) of sufficient length and spectrophotometer of sufficient performance to enable the absorption feature of chlorophyll-a to be identified at
