WebFeb 2, 2024 · Instrument calibration involves the construction of a calibration curve that allows to predict the concentration of an analyte in a sample from the reading of an instrument. This curve is the linear regression model that ‘best fits’ the relationship between some known concentration standards and the respective instrument responses. 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 problem of instrument calibration; other standard approaches may mix the standard into the unknow…
