摘要： An infrared spectrophotometer, which is capable of preventing measurement data measured from being adversely affected by moisture vapor. An internal space of an attachment receiving therein an optical element is sealed and isolated from ambient air by providing a tube and others, and a dehumidifier is provided in the internal space of the attachment for an optical path. Thus, the dehumidifier is disposed in a relatively narrow space, so that the internal space of the attachment can be efficiently dehumidified within a short period of time so as to reduce humidity in the internal space to suppress absorption of moisture vapor which would otherwise occur on the optical path in the internal space of the attachment. This makes it possible to prevent a negative influence of moisture vapor on measurement data, while reducing a standby time due to the dehumidification.

摘要： A nephelometric turbidimeter for measuring a turbidity of a liquid sample in a transparent sample cuvette. The nephelometric turbidimeter includes a cuvette chamber housing with a cuvette chamber having the transparent sample cuvette arranged therein, and a drying apparatus. The drying apparatus includes a cuvette chamber inlet opening which vents the cuvette chamber, a cuvette chamber outlet opening which de-vents the cuvette chamber, an air circulator which circulates air from the cuvette chamber outlet opening to the cuvette chamber inlet opening, and a drying body. The drying body is provided as a container of a hygroscopic agent defined by a drying substance which is arranged in a drying path between the cuvette chamber outlet opening and the cuvette chamber inlet opening so that air flows through the drying body.

摘要： An analysis method includes the steps of causing a moist sample to react with a reagent and measuring concentration of a particular component contained in the sample based on the state after the reaction of the sample with the reagent. The reaction step and the measurement step are performed while the amount of moisture contained in the air in a space accommodating the sample and the reagent is directly or indirectly measured. The method further includes the step of correcting the measurement result of the concentration of the particular component based on the amount of moisture contained in the air.

An incident light beam is established within the housing by a light source module that is releasably engaged with the first receptacle. A test liquid holder is removably engaged with the first receptacle. A test liquid holder is removably received by the second receptacle for positioning a liquid to be tested in the path of the incident beam. A photodetector or analogous instrument is provided at an angle to the incident light beam for sensing light scattered by the test liquid. An analyzer apparatus includes appropriate circuitry that is responsive to the photodetector for determining the turbidity of the test liquid.

摘要： The invention relates to a measurement apparatus for measuring the concentration of a gaseous substance. The apparatus comprises a light source, a light sensor, and a housing comprising at least one first housing member having a low thermal conductivity. A light path is formed from said light source to said light sensor, wherein the light path passes through a measurement region within said housing. The light source is configured to emit light with a spectral distribution such that said light is absorbed by said gaseous substance. Said light sensor is configured to receive the light emitted by the light source after it has passed through the measurement region. The first housing member comprises a thermal shielding region facing said measurement region on its one side and said light sensor on its other side, and is configured to permit the passage of light.
