Abstract: An inspection apparatus includes a measurement unit, a flow-in tube for flow of sample water into the measurement unit, a connection portion that connects a sample tube and the measurement unit to each other, a liquid sending portion that sends sample water to the measurement unit, a pressurization pump that increases a pressure in the inside of the sample tube, and a controller. The controller controls operations of the liquid sending portion and the pressurization pump to suppress within a prescribed range, variation in pressure applied to sample water until sample water reaches the measurement unit from the inside of the sample tube.

Abstract: An object is to increase an efficiency of removing carbon dioxide derived from inorganic carbon. An inspection apparatus includes: a column that separates a group of substances contained in an aqueous sample by size; an addition unit that adds a reagent, which acidifies the aqueous sample, into a channel; a degassing unit provided downstream of the addition unit for degassing carbon dioxide; a measurement unit that measures organic carbon contained in each substance from which the carbon dioxide has been removed; and a temperature maintaining unit that maintains a temperature of each of the column and a container in which a gas-permeable tube of the degassing unit is housed.

Abstract: A sample heating device includes: a rail-shaped disposal rail extending in one direction in a horizontal plane so that sample boats after heating are arranged and placed in a straight line; a disposal tray that houses the sample boat pushed-out from one end of the disposal rail; a sample boat conveying portion that places the sample boat after the heating at a predetermined placing position on the disposal rail; and a sample boat push-out portion that is positioned closer to the other end side of the disposal rail than the placing position when the sample boat is placed on the disposal rail and that is displaced toward the one end side of the disposal rail after the sample boat is placed at the placing position to slide the sample boats on the disposal rail toward the one end side.

Abstract: A sample heating device includes: an opening/closing cover provided to be movable in a horizontal direction between a position above an opening of a mounting port and a position displaced from the position above the opening, and a cover sliding mechanism that is engaged with a part of a sample boat conveying portion when the sample boat conveying portion comes to a predetermined position in a horizontal plane and moves the opening/closing cover in the horizontal direction according to upward and downward movements of the sample boat conveying portion so that the opening/closing cover is provided at the position directly above the opening of the mounting port when the sample boat conveying portion comes to a predetermined height.

Abstract: A control device controls driving of a pulse motor to cause liquid that is sucked into a syringe in a single suction process to be discharged over a plurality of discharge processes. The control method of the control device is a method that controls driving of the pulse motor so that rotation of a ball screw for executing each discharge process starts from an identical rotational angle position relative to a slit of a coupling.

Abstract: An infrared type gas analyzer is formed of a measuring cell for receiving a gas to be measured; an infrared light source for irradiating the gas in the measuring cell; a correlation filter disposed adjacent to the measuring cell; and a sensor for detecting infrared light ejected from the infrared light source and passing through the correlation filter and the measuring cell to analyze the gas in the measuring cell. A correction filter is disposed on a portion of the correlation filter for correction or calibration of the gas analyzer. Thus, the infrared type gas analyzer has a simple structure and can perform a simplified correction without complicated operation.

Abstract: Relation of the degree of interference to interference concentration is previously stored with respect to at least one interference gas influencing an oxygen indicated value of a sample gas, so that interference corresponding to interference gas concentration of the sample gas is corrected on the basis of the stored relation when oxygen concentration is calculated from a detection signal of an oxygen sensor and outputted. Concentration of the interference gas, with respect to which the relation of the degree of interference is stored, is manually inputted in measurement, or previously set. When the concentration of the interference gas is previously set, such concentration is made changeable by manual input. Thus, even if the sample gas contains an interference gas in high concentration as in the case of an exhaust gas containing highly concentrated CO.sub.2 gas, it is possible to accurately measure oxygen concentration of the sample gas.
