A method for on-site nickel measurements for the metal plating industry. The calibration takes about 3 minutes and is stable for several days. A measurement only takes about 30 seconds.
Determining Turbidity of an aqueous solution is a frequently used procedure to estimate the quality of water, or even concentration of suspended particles such as cells, bacteria and mud. Following the USEPA method and ISO 7027 method, the turbidity is measured at wavelengths of 570 nm and 850 nm respectively. This application note highlights the measurements of OD at these two wavelengths using the Photopette®.
