    摘要: A reference sample having a known concentration is injected into a chromatograph system before an unknown sample is analyzed. This is for the purpose of checking the deterioration of system performance or in other words for the purpose of checking system suitability. In the present invention, the chromatographic characteristic of the check sample at the time of deterioration of the system suitability is expected and stored in a memory in advance to be related to factors of deterioration of system suitability. A factor of deterioration is deduced by comparison between the actually analyzed chromatographic characteristic of the check sample and the relational data stored in the memory. A guidance required for removing the factor is displayed. Disclosed are preferred embodiments of a chromatograph system suitable for analyzing catecholamine or glycated hemoglobin.

    摘要: An autosampler consists of a needle to draw specimen from a specimen container into a passage therein; a block having a passage that follows the passge in the needle; a suction mechanism for drawing in the specimen by suction through the passages in the needle and the block; a discharge mechanism for discarding the specimen drawn in by the suction mechanism; and a detecting device for detecting air bubble in the specimen, the detecting device being embedded in the block in such a manner as to face the passage in the block. The detecting device detects the air bubbles in the specimen according to changes in physical or chemical properties of the specimen passing through the passage in the block. The discharge mechanism is activated by the detecting device to discharge air-mixed specimen. When even a small amount of air is drawn into the passage from the specimen container, in which only a small amount of specimen is contained, the air specimen can reliably be distinguished from normal specimen by this autosampler. Therefore the reliability of the system using the autosampler can be significantly improved.
