摘要： PURPOSE:To provide high sensitivity measurability for a specimen of a very small amount of attaching Au or Ag by evaporation onto a base board having good infrared penetrativeness, and thereby forming a metal file having a specific thickness. CONSTITUTION:Au or Ag is attached by evaporation onto a base board 2 having good infrared penetrativeness to form a metal film 3 having a thickness of 5-16nm, and thus a specimen holder member 1 is provided. A specimen is held on this member 1 and irradiated with infrared rays IR fed from a light source 4, and the spectrum after penetration of specimen and member 1 is measured by a Fourier transform type infrared spectral photometer (FT-IR) 5. According to this procedure, the infrared ray electric field intensity is intensified on the surface of the film 3, so that the infrared absorption intensity is intensified on the surface of the film 3, so that the infrared absorption intensity is exerted sufficiently, and consequently even a specimen of super-fine quantity can be measured with high sensitivity.

摘要： PROBLEM TO BE SOLVED: To accurately and quantitatively determine oxygen included in a sample such as a steel, even if an amount of the oxygen is a trace amount. SOLUTION: In this method, a sample 3 in a carbon crucible 2 is heated and melted while an inert gas 5 is supplied into an extraction furnace 1, a gas extracted at this time is introduced to a gas analyzer 7, a concentration of carbon monoxide is measured and an oxygen included in the sample 3 is quantitatively analyzed, based on the concentration of carbon monoxide. While an inert gas 5 is supplied into the extraction furnace 1, the carbon crucible 2 is heated at a predetermined temperature for a predetermined time at an empty state in order to degasify. Thereafter, the sample 3 is thrown into the carbon crucible 2 adjusted to the predetermined temperature and the carbon crucible 2 accommodating the sample 3 is primarily heated at a predetermined temperature for a predetermined time, while an inert gas 5 is supplied into the extraction furnace 1. Thereafter, a gas in the extraction furnace 1 is discharged by a suction, and then the carbon crucible 2 is secondarily heated at a predetermined temperature higher than the temperature at the primary heating, while the inert gas 5 is supplied into the extraction furnace 1.

摘要： PROBLEM TO BE SOLVED: To provide an analyzing apparatus for oxygen and/or nitrogen in a sample containing sulfur which can obtain highly reliable analyzing values by removing interfering/harmful components. SOLUTION: In the analyzing apparatus, a sample is heated and fused in an extraction furnace 1, a CO component in the extracted gas is analyzed by a CO analyzer 6 thereby obtaining an O2 component, and then the CO component is changed to CO2 by an oxidizing agent 7 and removed by an alkali reagent 8. Moreover, the remaining extracted gas is dehydrated by a dehydrating agent 9. Thereafter, an N2 component is obtained by an N2 detector 10. An MnO2 - filling pipe 5 is arranged in a flow path between the extraction furnace 1 and CO analyzer 6 so as to remove a CS2 component.

摘要： PURPOSE: To quickly analyze a sample solution with high sensitivity by supplying the sample solution to an ion exchange resin filling up a limited space in a cell. CONSTITUTION: A flow cell 5 has a space section 6 which is formed by recessing the bottom of its main body 51 composed of a resin material. A pipe 21 which is connected to a sample supply line 2 is introduced to the space section 6 from the top of the main body 51. On the other hand, the bottom of the space section 6 is covered with a window material 52 and an overflow line 9 is connected to the upper part of the section 6. Then the section 6 is filled with an ion exchange resin 7 and a sample solution in an injector 4 is supplied to the resin 7 through the sample supply line 2. Therefore, the sample solution can be analyzed quickly, because the sample solution widely comes into contact with the surface of fine grains of the resin 7 and a catalytic reaction can be accelerated half-forcedly. In addition, the sample solution can be analyzed with high accuracy, because the sample solution is measured in the cell 5 without dilution.

CONSTITUTION: A sample body comprises titanium 1 used as a sample, and a cylinder 2 made of bath metal, holding the sample, and titanium 1 is supported in almost the center in the lengthy direction of the cylinder 2 by bringing the inner projections 3 into contact with titanium 1. The sample body is formed in such a way that titanium 1 is loosely put in the cylinder 2 having a specified shape, positioned in the center in the lengthy direction of the cylinder 2, and the cylinder 2 is pressed from the side. Since the sample body is always formed in the specified size, it is not caught by a sample inserting port, and by forming a vent hole, air is surely purged without enclosure when the sample body is heated.
