abstract = "The Federal Bureau of Mines has derived a mathematical expression for the emulsion calibration curve used in optical emission spectroscopy. Employing a two-step preliminary curve method, an approximation of the first derivative of the calibration curve is formed and integrated. The
final equation is

*I* = (1 + β*S*)^{−α}

where *I* is the line intensity, *S* is the transform that linearizes the preliminary curve, and α and β are constants.",
