Abstract:
PROBLEM TO BE SOLVED: To provide a sampling device for liquid samples. SOLUTION: In a sampling device, a sample is transported through a capillary tube active channel from a sampling point to a measuring point and the capillary tube active channel comprises a supporting body, a cover, and an intermediate layer between the supporting body and the cover. The supporting body extends beyond the cover in the vicinity of the sampling point, and the intermediate layer retreats from the sampling point in the vicinity of the latter. This device can supply samples in the upper direction and in the lateral direction over the exposure region of the supporting body in the vicinity of the sampling point. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an inherent control system surely indicating the possibility that analytical elements are unusable, as a result of inappropriate storage or transport conditions. SOLUTION: A reagent system is used for the so-called "intrinsic control of an analytical element", specially a test strip, containing organic N-oxide or a nitroso compound, the analytical element includes both a reagent system for detection reaction and a reagent system for inherent control. In an analytical element inspecting method, the reagent system for inherent control is inspected optically or electrochemically, through the use of measuring apparatus to changes capable of indicating stress of the analysis element.
