Limit of linearity define
In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration. A calibration curve is one approach to the … Se mer In more general use, a calibration curve is a curve or table for a measuring instrument which measures some parameter indirectly, giving values for the desired quantity as a function of values of sensor output. For example, … Se mer Most analytical techniques use a calibration curve. There are a number of advantages to this approach. First, the calibration curve provides a reliable way to calculate the … Se mer • Color • Curve fitting • Linear regression • Logarithmic scale Se mer The operator prepares a series of standards across a range of concentrations near the expected concentration of … Se mer • Analysis of concentration • Verifying the proper functioning of an analytical instrument or a sensor device such as an ion selective electrode Se mer • Harris, Daniel Charles (2003).
