    摘要： PROBLEM TO BE SOLVED: To obtain an analyzer in which a calolific value can be measured at high speed and with high accuracy by using a chromatograph. SOLUTION: In a first analytical part 11, a component C3 or higher is excluded by a precolumn PC1, a valve V2 is changed over at a prescribed timing, oxygen, nitrogen and methane are separated by an MS-5A column MC2, and carbon dioxide and ethane are separated by a polymer bead column MC3. On the other hand, in a second analytical part 12, a component C6 is excluded by a precolumn PC2, and the component C3 to a component C5 are separated by an alumina plot column MC4. When the step-up control of the entrance pressure of the column MC4 is used jointly, a GC analysis can be finished within about 3 minutes. The concentration of every component is calculated by the GC analysis, it is multiplied by the correction factor of a heat quantity, its total sum is calculated, and a calolific value is found. The concentration of components other than a component, to be analyzed, which contains the component C6 is estirrsated in such a way that the pressure of the concentration of every component obtained as a result of the GC analysis is corrected and that the concentration is estimated from the deviation amount of the total sum of the corrected concentration from 100%.

    摘要： PROBLEM TO BE SOLVED: To provide a VOC concentration meter for accurately measuring the concentration even when the VOC concentration in indoor air is low, and to provide a VOC removing system for accurately measuring the concentration and exhausting VOC outdoors even when the VOC concentration in indoor air is low. SOLUTION: The VOC concentration meter comprises a reproducible VOC adsorbing means; a blowing means for generating an airstream passing the VOC concentration meter; a reproducing means that is arranged on the upstream side of the VOC adsorbing means with respect to the airstream and reproduces the VOC adsorbing means; and a VOC sensor arranged on the downstream side of the VOC adsorbing means with respect to the airstream. When the reproducing means reproduces the VOC adsorbing means, the VOC sensor measures the concentration of the concentrated VOC exhausted from the VOC adsorbing means. COPYRIGHT: (C)2006,JPO&NCIPI

    摘要翻译： 要解决的问题：为了提供即使当室内空气中的VOC浓度低时精确测量浓度的VOC浓度计，并且提供用于在室外精确测量浓度并排出VOC的VOC去除系统，即使当VOC 室内空气浓度低。 解决方案：VOC浓度计包括可再现的VOC吸附装置; 用于产生通过VOC浓度计的气流的吹风装置; 相对于气流配置在VOC吸附装置的上游侧的再现装置，再现VOC吸附装置; 以及VOC传感器，其相对于气流排列在VOC吸附单元的下游侧。 当再现装置再现VOC吸附装置时，VOC传感器测量从VOC吸附装置排出的浓缩VOC的浓度。 版权所有（C）2006，JPO＆NCIPI
