Abstract: The purpose of the present invention is to provide a charged particle beam device and a sample holder for the charged particle beam device by which it is possible to form various environments, and perform in-situ observation and analysis without removing a sample from the charged particle beam device. In the present invention, inserting a detachable reverse side entry portion from a side facing a sample holding means, said portion being provided with a function for changing the state of a sample attached to the sample holding means, makes it possible to observe/analyze changes in the sample by a different process without removing the sample from the charged particle beam device by combining a reverse side entry portion having a different function with the sample holding means. The reverse side entry portion comprises two parts, and a tip thereof, which is one of the parts, is removable.

Abstract: A focused ion beam apparatus includes a sample tray on which a sample is placed, and a focused ion beam column for irradiating the sample with a focused ion beam to obtain a micro sample-piece. A sample chamber contains therein the sample tray and the focused ion beam column. A side-entry-type carrier is inserted into and removed from the sample chamber, with a front end side of the carrier holding the sample-piece. A sample-piece moving unit moves the sample-piece between the sample tray and the carrier. The sample tray is movable along at least x, y, and z axes, and an end of the sample tray is provided with a carrier engagement part releasably engageable with the carrier so that movement of the sample tray is accompanied by corresponding movement of the carrier.

Abstract: In a urine component analysis device, a correlation storage section stores data indicating a correlation between a measured concentration in one urine and in total urine in one day for each of a first and second specific component in the urine excreted by a human. A data input section inputs data indicating a concentration of the first specific component and of the second specific component in one urine of a subject. A concentration of the first specific component and of the second specific component in total urine in one day are determined by performing conversion using the correlation stored in the correlation storage section based on the concentration of the first specific component and the second specific component in the one urine. A concentration ratio between the first specific component and the second specific component in total urine in one day is determined based on the results of conversion.

Abstract: A urine component analysis device with a correlation storage section stores data indicating a correlation between a measured concentration of a specific component in human urine and measured concentration of the specific urine component in one day. A data input section inputs data indicating concentration of the specific component in one subject's urine. A concentration of the specific component in total urine of the subject in one day is determined by conversion using the correlation storage section based on the concentration of the specific component in the urine. A total urine amount acquirement section acquires total amount of urine excreted by the subject in one day based on conversion or database. An excretion amount of the specific component in total urine of the subject in one day is calculated by multiplying the concentration of the specific component in total urine in one day, by the acquired total urine amount.
