Abstract: A simple and convenient analyzing apparatus is provided which easily, conveniently, and efficiently collects a material in the state of fine particles adhered to a target object, extracts the object to be analyzed, and analyzes the extracted object. An apparatus for detecting fine particles in a gas which sucks the gas under measurement from the target object by using a suction pump, extracts the fine particles contained in the gas under measurement, and performs measurement by using a spectrometer is embodied such that an inertial impactor for collecting the fine particles having diameters not less than a specified particle diameter is disposed upstream of the spectrometer, the fine particles are collected in the fine particle collector of the inertial impactor, the collector containing the collected fine particles is heated such that the collected fine particles are vaporized into a gas, and the vaporized fluid to be examined is supplied to the spectrometer to be measured thereby.

Abstract: An explosive detection system including a sample injection region, an ion source region for generating ions of a sample injected by the ion injection region, a mass analysis region for analyzing mass of the ions, a heater for heating the sample injection region and the ion source region, a plurality of pumps for exhausting a chamber in which the mass analysis region is disposed, and a controller for controlling the regions and the plurality of pumps. The controller conducts control so as to heat the sample injection region and the ion source region with the heaters, then reduce heating electric power supplied to the heaters in order to prevent a predetermined electric power value from being exceeded, and drive the plurality of pumps successively to exhaust the chamber.

Abstract: A substance detection method includes the steps of: heating a sample adhered to a substance with a temperature at which the substance is readily vaporized to vapor the substance; sucking air and feeding the sucked air in a direction different from a direction along which the substance is vaporized; negatively ionizing the vapor sucked with the air; and detecting the substance adhered to the sample by analyzing the negative ion.

Abstract: A process for producing a liquid-container material that includes a thermoadhesive resin film, a substrate sheet having a thin-film layer of an inorganic compound, such as a silicon oxide, and a paper substrate. The thermoadhesive resin film is formed by melt-extruding a thermoadhesive resin from an extruder die, and then cooled to a temperature at which the thermoadhesive properties inherent in the thermoadhesive resin film can be retained and at which no crack is produced in the thinfilm layer of an inorganic compound when the thermoadhesive resin film is laminated to the substrate sheet. The cooled thermoadhesive resin film is laminated to the substrate sheet to form a laminate, which is then laminated to the paper substrate. The thermoadhesive resin film may preferably include a non-adsorptive resin layer and a thermoadhesive resin layer. In this instance, the non-adsorptive resin layer is so provided as to be on the outside of the liquid-container material.
