Water Nutrient Analysis

As a leading provider of environmental analytical services, CD BioSciences has dedicated decades of expertise to perfecting our water nutrient analysis capabilities, empowering our clients to make informed decisions and protect the delicate balance of our water resources.

• AHP-PCA (Analytic Hierarchy Process-Principal Component Analysis): A powerful multivariate technique that integrates expert knowledge and statistical analysis to prioritize the influential factors contributing to eutrophication.
• TSIM (Modified Trophic State Index Method): A refined version of the widely-used Trophic State Index, offering a more nuanced and contextualized evaluation of the water body's nutrient status.
• TLI (Trophic Level Index): A comprehensive approach that considers the interplay between various trophic levels to provide a holistic assessment of the ecosystem's eutrophication risk.
• SCO (Scoring Method): A systematic scoring system that synthesizes multiple water quality indicators to derive a consolidated eutrophication evaluation.

• Parametric, Biological, and Comprehensive Water Quality Identification Index Methods: A suite of complementary techniques that leverage both quantitative and qualitative data to paint a detailed picture of the water body's trophic condition.
• Fuzzy Mathematical Operation, Gray Clustering, and Gray Situation Decision Methods: Advanced mathematical and statistical approaches that account for the inherent uncertainties and complexities associated with eutrophication assessment.
• Neural Network Modeling: The application of artificial intelligence and machine learning to detect patterns, identify relationships, and predict eutrophication trends within the water system.

Flow Injection Analysis (FIA)

The FIA instruments' automated chemistry analyzers, combined with their high-speed sample processing capabilities, enable CD BioSciences to deliver results to our clients quickly, empowering them to make timely decisions regarding water treatment and nutrient management.

Segmented Flow Analysis (SFA)

Our SFA system is particularly adept at analyzing Total Phosphorus, Ammonia, and Nitrate/Nitrite. The inline digestion step integrated into the SFA process eliminates the need for separate digestion preparation, improving quality control and reducing the likelihood of re-analysis.

Specialized Techniques for Low-Level Detection

In cases where the lowest possible detection limits are required, our team of scientists utilizes manual spectrophotometric methods with specialized longer path cuvettes. This approach enables us to accurately measure nutrient concentrations at the parts-per-billion (μg/L) level, ensuring that even trace amounts of these critical parameters can be identified and addressed.

Ion Chromatography

For quantitative results on individual nutrient constituents, such as Nitrate and Nitrite, CD BioSciences employs Ion Chromatography, a complementary analytical technology that provides our clients with comprehensive and precise nutrient profiles.
