1. A sample analysis method comprising:
- a first step of confirming that a sample is supplied to an analytical tool based on output from the analytical tool;
a second step of grasping a level of the output from the analytical tool in a predetermined time period after the supply of the sample to the analytical tool is confirmed, the grasping being performed at least once including at a time point when the predetermined time period has elapsed; and
a third step of performing computation necessary for the analysis of the sample;
wherein the grasping of the output from the analytical tool in the first step and the second step is performed based on output from a double integration circuit which is obtained by inputting the output from the analytical tool into the double integration circuit;
wherein the first step comprises grasping a level of the output from the double integration circuit repetitively at first time intervals each defined by a time period from when the inputting into the double integration circuit is started till when the outputting from the double integration circuit is finished; and
wherein, in grasping a level of the output from the double integration circuit in the second step, a second time interval defined by a time period from when the inputting into the double integration circuit is started till when the outputting from the double integration circuit is finished is set longer than the first time interval.

Abstract
The present invention relates to a technique for analyzing a sample by utilizing a double integration circuit (11) for outputting a physical quantity related to the output from an analytical tool (2). In the present invention, the time interval from when the output from the analytical tool (2) is inputted into the double integration circuit (11) till when the physical quantity is started to be outputted from the double integration circuit (11) differs before and after the supply of the sample to the analytical tool (2) is confirmed.

9. A sample analysis apparatus to be used with an analytical tool mounted thereto for analyzing a sample supplied to the analytical tool based on output from the analytical tool, the apparatus comprising:
- a double integration circuit into which the output from the analytical tool is inputted and which outputs a physical quantity related to the input; and
a controller for controlling timing at which the output from the analytical tool is inputted into the double integration circuit and timing at which the physical quantity is outputted from the double integration circuit;
wherein the controller performs control so that a time interval from start of the inputting into the double integration circuit till start of the outputting from the double integration circuit becomes longer in a state after the supply of the sample to the analytical tool is confirmed than in a state before the supply of the sample to the analytical tool is confirmed. - View Dependent Claims (10, 11)
