  • Method for analyzing samples and device for analyzing samples
    Patent number: 11169071
    Abstract: In a method for analyzing samples involving the use of a device for analyzing samples, the device for analyzing samples includes at least a movement part through which a sample moves, and a measurement unit that is formed in a middle of the movement part and that measures a value of an ion current when the sample passes through the movement part. The analysis method includes at least a measurement step for measuring the value of the ion current when the sample passes through the movement part, and a determination step for determining a change over time in a quantity of ions from the value of the ion current measured in the measurement step. The quantity of ions includes a quantity of ions that have leaked from the sample during movement of the sample through the movement part.
