Online fluorescence spectrum analyzer for algae in water

The online analyzer of algae fluorescence spectrum in water is an online analytical instrument for algae classification and measurement using discrete three-dimensional fluorescence spectrum technology. Using the three dimensional fluorescence spectrum contains the rich algae pigments "fingerprints" of information, combined with aliasing fluorescence spectrum analysis method, realize the cyanobacteria, green algae, diatoms and dinoflagellates main algae and hidden algae such as sea lake library accurate identification and accurate quantitative analysis of chlorophyll concentration, community recognition accuracy and chlorophyll quantitative accuracy is superior to the similar equipment.

On-line rapid monitoring instrument for heavy metals in water

Laser-induced breakdown spectroscopy (LRT) uses high-energy pulsed laser to generate plasma and analyze the plasma spectrum, so as to quickly obtain the information of elements and their content in the sample. Water enrichment of heavy metals using graphite substrate automatic fast on-line monitoring to dry technology, enrichment of heavy metals in water body to properties on the stability of the graphite, at the same time combined the technology of plasma space constraints and the heavy metal accurate quantitative inversion algorithm, realized the fast online monitoring of heavy metal water, for water heavy metal pollution in real-time monitoring, water environmental restoration, etc. To provide technical support.

In situ monitor of algae community and chlorophyll concentration in water

The in situ monitoring instrument for algae community and chlorophyll concentration in water body is the first in the world to realize the classification and measurement of algae by using discrete three-dimensional fluorescence spectroscopy. Using discrete three-dimensional fluorescence spectrum contains the rich algae pigments "fingerprint" information, combined with aliasing fluorescence spectrum analysis method, realize the advantage of diatoms, dinoflagellates, green algae, and other Marine algae accurate identification and accurate quantitative measurement of chlorophyll concentration, algae community is rapid in situ monitoring of advanced tools, community recognition accuracy and chlorophyll concentration is obviously better than the accuracy of quantitative international similar instruments.

In situ monitoring of water buoy primary productivity

Primary productivity (GPP) refers to the total amount of fixed organic matter produced by phytoplankton in unit time and unit volume through photosynthesis, which is the basis of carbon cycle in global ecosystem. Quantitative assessment of the primary productivity of Marine phytoplankton is an important link in the study of Marine ecosystem.

Comprehensive toxicity online monitor for water body

The online monitoring instrument for comprehensive toxicity of water is an online monitoring instrument for detecting the comprehensive toxicity intensity of water by using the changes of photosynthetic activity of planktonic algae under the stress of toxic pollutants. The instrument uses chlorophyll fluorescence as the probe of algae photosynthesis process to detect the photosynthetic activity of algae rapidly and nondestructively. The inhibition rate of photosynthetic activity of algae under toxic stress was obtained by the "control-test" dual channel test. Based on the dose-effect relational database between the toxicity intensity of pollutants and the photosynthetic inhibition rate of algae, combined with the threshold model of environmental stress, the rapid monitoring of comprehensive toxicity intensity of water and the real-time warning of ecological environmental risks were realized.
