Abstract: The analysis apparatus according to the present invention is capable of setting parameters and user authentication, which do not require key input. When a specific analysis apparatus is set so as to measure a specific type of data, a plurality of required parameters are converted to data having a format suitable for a relay medium and the converted data is recorded in the relay medium. An importing unit imports the plurality of parameters from the relay medium. A restoration unit is used to obtain, from the imported parameters, each parameter in the pre-conversion format thereof. The individual obtained parameters are transferred to a setting unit and set to a required setting destination. This being the case, the replay medium is created according to the support from a management device of a manufacturer and a repeater.

Abstract: This laser gas analysis device compensates distortion of a laser beam and can place a detector depending on the wavelength used. A transmitter side process window unit consists of two wedge-shaped glass substrates that are positioned to have a space with an appropriate length along a laser propagation direction, and sends the laser beam from a transmitter unit to a measuring space. A receiver side process window unit is configured the same as the transmitter side process window unit, and sends the laser beam passed through the measuring space to a receiver unit. The outer surfaces of the two wedge-shaped glass substrates with respect to the space in between are placed to be parallel each other, and accordingly the inner surfaces are also parallel each other. The distance between the two wedge-shaped glass substrates in the laser propagation direction is determined so as to avoid optical interferences of the laser.

The constant k1 may employ the temperature dependency of electric conductivity of metal used to the rotator.

Abstract: A conductive rotator is immersed in a sample liquid in a sample container. A magnet is arranged at a specific distance from the rotation plane of the rotator in a direction of a rotating axis of the rotator so as to face the sample container. The magnet applies a magnetic field to the rotator from the outside of the sample container. A fluctuating magnetic field drive unit drives the magnet to apply the magnetic field that fluctuates in term of time to the rotator. Induced current is excited in the rotator by the fluctuating magnetic field. A rotating torque is provided to the rotator by the Lorenz interaction between the induced current and the fluctuating magnetic field, and as a result, the rotator rotates in the rotation plane. A viscosity detecting unit obtains the viscosity of the sample liquid based on a rotating state of the rotator and a time-fluctuating state of the fluctuating magnetic field.

Abstract: In the invention, a back titration and titer determination can be made using a back coulometric titration. When the iodine exists in a solution put in the titration flask with electrolytic electrodes, a back coulometric titration is performed to produce iodine ions from the iodine at the anode of the electrolytic electrodes. Where the solution is a dehydrated solvent including a Karl Fischer reagent for a volumetric titration, the titer can be determined by the back coulometric titration. Where the solution is anolyte in which the iodine remains after the coulometric titration in the coulometric titration method, the water content in the sample is found from the quantity of electricity consumed by the coulometric titration and the quantity of electricity consumed by the back coulometric titration.

The predetermined amount corresponds to the volume of the sample to be introduced in the oscillatory densitometer, the density is a measurement result of the oscillatory densitometer, and the thermal time constant corresponds to the time constant of the oscillation period of the oscillatory densitometer.
