Patent ID: 8623656

Claim:
A method of analyzing a third chemical substance for a quantity of (i) at least one of a first chemical substance and a second chemical substance and/or (ii) a product of a reaction between the first chemical substance and the second chemical substance, the method comprising: preparing a calibration curve by: ejecting droplets of a liquid comprising the first chemical substance for a positive integer number of times to plural independent positions on a first substrate by an inkjet system to apply the first chemical substance for the positive integer number times of an amount contained in one droplet; ejecting droplets of a liquid comprising the second chemical substance, which can react with the first chemical substance, for a positive integer number of times to positions where the first chemical substance is applied by an inkjet system to apply the second chemical substance for the positive integer number times of an amount contained in one droplet, to thereby prepare a standard sample; performing a quantitative analysis of the standard sample; and forming the calibration curve based on a result of the quantitative analysis of the standard sample; performing a quantitative analysis of the third chemical substance provided on another substrate; and Determining, in the third chemical substance, the quantity of (i) at least one of the first chemical substance and the second chemical substance and/or (ii) the product of the reaction between the first chemical substance and the second chemical substance by using a result of the quantitative analysis of the third chemical substance and the calibration curve, wherein, in the preparing of the calibration curve, the droplets are ejected such that the first chemical substance and the second chemical substance are mixed on the applied positions and are at least partially reacted.
