A Low-Cost Light-Scattering Detector for the Flow-Injection Nephelometric Determination of Sulfate
A simple low-cost flow-through light-scattering detector was developed for determining the particle mass concentration in colloidal suspensions.

| Summary: | A simple low-cost flow-through light-scattering detector was developed for determining the particle mass concentration in colloidal suspensions. Employing a laser pointer as a light source and a photodiode IC as a light sensor, the detector was shown to have good sensitivity, yet was small and battery operated. The detector was demonstrated to be effective for the flow-injection nephelometric determination of sulfate by precipitation as barium sulfate. |
