Instran Online Nickel Concentration Meter
Continuous measurement of nickel concentration in water is possible!
Method - Colorimetric Analysis After the sample is introduced into the measurement cell, several reagents are added to adjust the solution conditions (such as pH and the valence of elements). Subsequently, a blank measurement is performed to correct for the effects of temperature and turbidity. Next, the final reagent is added, which reacts with the solution to produce a color that is measured at the appropriate wavelength. Depending on the photometer used, the results are obtained with very high precision. The optimal pH conditions are established using an acetate buffer, and Br-PADAP reacts with nickel to form a strong pink color that is proportional to the nickel concentration. The pink color formed can stain the measurement cell and interfere with subsequent measurements; however, this interference is removed by a cleaning solution from Instran. *Substances that may interfere: Cobalt*
