Conductivity (or specifically electrolytic conductivity) is the ability of a substance to conduct electric current.

Standard Addition Method

Introduction In analytical chemistry, a calibration equation generally serves in determining the unknown concentration of an analyte. Developing the equation entails evaluating the sensor’s response to a series of standards with known concentrations of the same analyte. The calibration equation method normally requires an identical matrix for both sample and standards without interference with the […]
