摘要:
An analytical element and method using the element for measuring a specific component in a fluid sample such as blood, serum, plasma, urine, sweat etc. The fluid sample is applied on the element with a labeled-material formed by binding the specific component or the analogue of it with a labeling material causing a signal. The element comprises a reaction layer and an absorption layer. The reaction layer contains a material which is capable of specifically binding with the component to be measured and the absorption layer contains a material which capable of binding with the labeled material and decreasing a signal caused by the labeling material. A strength of the signal caused labeled-material in the reaction layer is determined to measure the specific component.

摘要:
A compound container which is comprised of a container main body 2 forming a first accommodation chamber 20 and an auxiliary container 3 forming a second accommodation chamber 30, wherein a mounting part 22 on which the auxiliary container 3 is mounted is provided in the container main body 2 and a cutting part 221 which cuts a second accommodation chamber partition wall 30a which partitions part of the second accommodation chamber 30 formed in the auxiliary container 3 is formed, and when the auxiliary container 3 is mounted on the container main body 2, the second accommodation chamber partition wall 30a is cut, whereby the first accommodation chamber 20 and the second accommodation chamber 30 are intercommunicated. As a result, if contents which are needed to be heat-treated are heated while keeping the state where the contents are sealed within the container, the contents which are sealed in a plurality of accommodation chambers formed in the container can be mixed while keeping the contents being isolated from the outside environment by effectively preventing the contents to be heated from leaking outside as well as by preventing deterioration of sealing performance.
摘要:
A method for producing aluminum hydroxide includes a step of elevating a temperature of a slurry of aluminum hydroxide suspended in a sodium aluminate solution from 70° C. or lower to 85° C. or higher, and a step of applying a centrifugal force to the slurry. The aluminum hydroxide constituting the slurry is obtained beforehand through the Bayer's process.
