    摘要： The object of this invention is to provide an atomic absorptiometer and a metal specimen atomic vapor generation apparatus used in the atomic absorptiometer, which enable a light absorption measurement based on the Zeeman effect highly capable of background correction and eliminate the need for the troublesome work of dismounting a magnet. For this purpose, the following configuration is employed. First, the specimen, hydrochloric acid, and sodium borohydride are delivered and mixed by the peristaltic pump 10 to produce a metallic hydride. The generated gas-liquid mixture solution is separated by the separator 12 into a specimen gas and liquids. The separated specimen gas is introduced into the heating section 30. Electricity is supplied from the power source 28 to the specimen heating section 30 where the specimen gas introduced is heated and separated into hydrogen and a specimen metal vapor to be measured. The specimen metal vapor is then introduced into the measuring section 34 arranged between magnetic poles of the magnet 32 where the metal vapor is subjected to the atomic absorptiometric analysis based on the Zeeman effect.

    摘要： A method and an apparatus for adjusting the resistance value of a thermal head assembly. One voltage pulse or a set of voltage pulses of a preselected peak value are impressed on the heat generating resistor elements of the thermal head assembly. The resistance values of the resistor elements are then measured and compared with the predetermined target value. If the measured resistance values are above the target value, the resistor elements are subjected to another pulse or set of pulses having a peak value a little higher than the preceding one. Then, the resistance values are again measured and compared with the target value. Thus, the resistance values are decreased by successively impressing voltage pulses with the peak value thereof being increased little by little, until the resistance values become lower than the target value.

    摘要： The present invention provides a capillary electrophoresis apparatus in which a capillary is easily attached to and detached from a migration medium filling unit without mixing impurities into the capillary. Mixture of impurities such as dust is also prevented when a capillary negative-electrode end is brought into contact with a sample stored in a vessel. Furthermore, temperature control is efficiently performed in the capillary. In the capillary electrophoresis apparatus, the whole of capillary array can be supported by grasping a grip portion by hand. A migration medium filling mechanism includes a slide mechanism which moves a polymer block with respect to a capillary head. The capillary electrophoresis apparatus includes a vessel in which a sample and a buffer can simultaneously be stored. Temperatures of the capillary and an irradiation and detection unit are controlled by a temperature control function provided in a thermostatic device.
