Patent DE-19910436-A1 (DE)
Title: Apparatus for highly sensitive detection of photosynthesis herbicides in water, e.g. for toxicity testing of drinking water, comprising fluorometer for determining effect on chlorophyll fluorescence in biological samples
Inventor: SCHREIBER ULRICH
IPC: G01N33/18
Filed: 1999-03-10
Abstract: In apparatus for detecting photosynthesis herbicides (I) in water, by determination of chlorophyll fluorescence and quantum yield in biological samples, (i) a stronger light flash is used before establishing the fluorescence yield; and/or (ii) 2 identical chambers are used for the fluorescence determination, each containing a suspension of the sample either in the test water or in pure water. Apparatus for detecting contamination of water by photosynthesis herbicides (I), by determination of chlorophyll fluorescence and the photochemical quantum yield of photosystem II in photosynthetically active biological samples (II), uses measuring light pulses to establish the fluorescence yield and saturating light pulses in the second region to give the maximum fluorescence yield (Fm).  The novelty is that: (i) before establishing the actual fluorescence yield (F), a stronger flash of light (pre-flash) is applied, so that each photosystem II unit lacks at least one light quantum, and the time between the pre-flash and establishing the actual fluorescence yield is adjusted (to ca. 1 second), such that the fluorescence increase induced by the pre-flash is relaxed in non-inhibited photosystem II units, while it remains in inhibited photosystem II units; and/or (ii) two identical adjusting measuring chambers are used for the fluorescence determination, one containing a suspension of (II) in the water to be tested and the other containing a suspension of (II) in pure water, so that illumination of the two samples to determine the fluorescence yields F and Fm are carried out under identical conditions and the ratio of the quantum yields determined from these measured values gives the percentage inhibition of photosynthesis by (I) in the water to be tested.
