Provided are a quantification method and a quantification device capable of performing measurement at high sensitivity and high accuracy on a sample that contains sodium ions such as a biochemical sample, a pharmaceutical product, and food. The quantification method includes a calibration curve preparing step to measure a standard solution, which has been prepared by adding sodium ions so that a sodium ion content of the standard solution is equaled to a sodium ion content of a sample to be measured with a method employing a reaction that activates a limulus reagent and/or a biochemical luminescent reaction caused by ATP, luciferin, and luciferase, and to prepare a calibration curve that represents a relation between a measurement value and an amount of a component to be measured; a sample measuring step to measure the sample to be measured with a method being the same as that used in the calibration curve preparing step; and a quantifying step to find, by using the calibration curve, an amount of the component to be measured in the sample to be measured from a measurement value in the sample measuring step. |
