Nitrate Biosensor - Case Study

BACKGROUND In 1998, Dr. Bill Campbell and his team published a peer-reviewed journal article in Analytical Chemistry on the construction and characterization of Nitrate Reductase-Based Amperometric Electrode and Nitrate Assay of Fertilizers and Drinking Water. This publication set the stage for the nitrate biosensor project. In this publication, we found that nitrate reductase was indeed capable ...

mini LoP improved performance - Case Study

Meeting very stringent total phosphorous requirements is a challenge for a treatment plant that is receiving wastewater from a dairy process. With a total phosphorous limit less than 100 ppb, a ...

For Highly Dynamic Measurements in Extreme Environments: Piezoelectric Pressure Sensors

If you have to measure high pressure peaks or pressure surges at simultaneously high temperatures or a high base load, you’ll need special pressure sensors. As a solution-oriented supplier of pressure and level measurement technology, BD | ...

Total Phosphorus Water Quality Online Automatic Analyzer

Under neutral conditions, the sample is digested by potassium phosphorus converting all of phosphorus into orthophosphate. Then under acidic conditions, orthophosphate reacts with molybdate and oxygen antimony potassium tartrate, generating phosphomolybdic acid that is reduced by ascorbic acid to form blue complex. The amount of blue complex is proportional to orthophosphate. Measurement by ...
