Abstract: Please substitute the new Abstract set forth below for the original Abstract: The object of the invention is to perform, rapidly and at a low cost, a pretreatment of an analysis sample containing a turbid substance. Provided is an analysis sample pretreatment apparatus in which a clarified liquid is obtained by removing a turbid substance from an analysis sample. The analysis sample pretreatment apparatus includes a cell configured to store the analysis sample, and a cell holder in which at least a part of a housing is opened to mount the cell. The cell holder includes an ultrasonic wave transducer and an ultrasonic wave reflection plate that are disposed on facing plane pairs while sandwiching the cell mounted inside the cell holder. The cell includes a first opening unit from which the analysis sample flows in, a second opening unit from which the clarified liquid flows out, and a third opening unit from which the turbid substance is discharged. In a state where the cell is mounted in the cell holder, the first opening unit is provided at a position lower than an upper end of the ultrasonic wave transducer in a vertical direction, or at a position higher than a lower end of the ultrasonic wave transducer in the vertical direction.

Abstract: The present disclosure proposes a mass spectrometer including a linear ion trap section and an analyzer that analyzes the ions ejected from the linear ion trap section having a multipole rod electrode including a plurality of segments arranged in a direction of a center axis of the linear ion trap section. A first radio frequency voltage in opposite phase is applied to adjacent rod electrodes. An electrostatic voltage having the same amplitude and a second radio frequency voltage are applied to the segments having the same position in the direction of the center axis. The electrostatic voltage is applied to the segments such that the electrostatic voltage decreases from an inlet to an outlet of the linear ion trap section. The second radio frequency voltage is applied to the segments such that the second radio frequency voltage increases from the inlet to the outlet of the linear ion trap section.

Abstract: The invention optically analyzes a component in a sample having a material suspended. An optical analysis system that irradiates a liquid sample with light and analyzes a component of the sample using transmitted light transmitted through the sample includes a container accommodating the sample and an ultrasonic irradiation unit irradiating an ultrasonic wave for exciting the sample. The container includes a pair of light transmission wall portions between which the sample is disposed and which has light transmissivity, and one of the light transmission wall portions and the other of the light transmission wall portions are disposed to be separated from each other at a distance shorter than a wavelength of the ultrasonic wave.

Abstract: An object of the invention is to provide an optical analysis method and an optical analysis system capable of accurately performing an optical analysis by using transmitted light even though a sample contains a turbid substance. The optical analysis method of the present disclosure is an optical analysis method for irradiating a sample s containing a turbid substance in a cell 11 with light and performing optical analysis on the sample s by using transmitted light of the light. The optical analysis method includes: exciting the sample s in the cell 11 by irradiation with ultrasonic waves while adjusting a frequency of the ultrasonic waves such that an intensity of the transmitted light is maximized, and then performing the optical analysis in a state where the sample s is irradiated with ultrasonic waves of this adjusted frequency.
