Chlorophyll Detection of Algae

Chlorophyll is a photosynthetic green pigment found in algae and cyanobacteria that can be extracted and measured as a proxy for water body productivity or biomass. Chlorophyll can be used as an approximate measure of current biomass. The high nutrient content and specific climatic conditions in the water promote the growth of true algae and cyanobacteria (blue-green algae). As a result, algal blooms may develop, resulting in huge ecological and economic losses. Therefore, there is a strong interest in detecting algal growth at an early stage and continuously monitoring it. Chlorophyll molecules have good fluorescent properties in intact photosynthetic systems, allowing easy and sensitive determination of chlorophyll content. With proper excitation by different colored LEDs, the fluorometer can accurately determine chlorophyll content and distribution to different algae classes in real time. In addition to chlorophyll, the presence of various pigments resulted in typical spectral fingerprints. The scientists of CD BioSciences use a simpler and more effective chlorophyll sensor. Since all phytoplankton contain chlorophyll, these organisms can be detected in situ using chlorophyll sensors

Method in Chlorophyll Detection Service

Our scientists use chlorophyll sensors to assess the chlorophyll concentration levels of phytoplankton in water samples. Chlorophyll is measured in micrograms per liter (µg/l). Fluorescence means that chlorophyll emits lower energy light (650-700 nm) when exposed to higher energy wavelengths (around 470 nm). The returning light can then be measured to determine how much chlorophyll is in the water, and in turn, estimate the concentration of phytoplankton.

The advantages of in vivo fluorescence measurement are:

• High sensitivity
• No sample preparation
• Rapid performance
• Low costs
• Real-time measurement with automatic turbidity correction
• Wireless measurement, easy to operate
• Calibration with live algal cultures

Sample Requirement

• Test samples will not be returned, please back up by yourself.
• The determination of chlorophyll concentration of each sample will be repeated more than 3 times.
• The type of algae sample is not limited.
• For breeds with special requirements or rare breeds, please contact our staff for more information.
