WebChlorophyll-a concentration is one of the most measured metrics in both water quality and plant health monitoring. It is an indicator of algal biomass and provides insight into stressors such as eutrophication and bloom risk. WebWe measured chlorophyll a and b and carotenoid contents, as well as all structural traits, with the community weighted means approach. We determined chlorophyll a and b and carotenoid contents with a UV/VIS Spectrophotometer (UV-1800PC, Shanghai Mapada Instruments Co., Ltd., Shanghai, China).

Webnutrient concentration (0, f/4, f/2 and f) for up to 60 days (with temperature 11°C and salinity 30ppt). Chlorophyll a (Chl a) content was measured by spectrophotometry. Results indicated that Chl content varied with different culture conditions and species. WebSep 19, 2024 · If a known concentration of chlorophyll-a is measured, then ε (at 430nm or 662nm) can be calculated by ε = A/c. Kinetics – change in concentration over time Chemical kinetics is the study of reactions over time. Using a spectrophotometer, we can monitor a chemical reaction as it occurs in real-time.
