Abstract: It has been difficult to conduct high-sensitivity, high-precision measurement due to externally generated contamination or cross-contamination. Thus, the invention includes (1) a filter unit having a filter at a bottom of a container for holding a liquid, the filter being adapted to filter a liquid, and (2) an attachment cover having a first opening and a second opening, the filter unit being attachable to and detachable from the attachment cover via the first opening, and the attachment cover being adapted to, when the filter unit is attached to the attachment cover, allow filtration by the filter in a state in which an inner face of the attachment cover is tightly in contact with an outer face of the filter unit, and discharge a resulting filtrate through the second opening.

Abstract: A laser beam 6 irradiated from a side face of a microchip 1 in which plural channels 2 fill ed with a member of a refractive index n2 in an inner portion of a member of a refractive index n1 (n2 lower base, and is deviated swiftly from a channel array. Hence, the laser beam 6 is made to be deviated gradually from the channel array by irradiating the laser beam 6 from the side face of the microchip 1 by being inclined relative to the same plane in a direction of being directed from the lower base to the upper base. As a result, a larger number of the channels 2 can efficiently be subjected to laser beam irradiation.

Abstract: The objective of the present invention is to simply perform image observation through transmitted charged particles. A sample irradiated by a charged particle beam is disposed directly or via a predetermined member on a light-emitting element (23) whereinto charged particles that have traversed or scattered inside the sample enter, causing a light to be emitted therefrom, which is collected and detected efficiently using a light transmission means (203) to generate a transmission charged particle image of the sample.
