Sample dispensing apparatus and automatic analyzer using the same |
摘要 |
<p>A sample dispensing apparatus is realized which can detect a dispensing abnormality occurred during the sample dispensing operation regardless of the type and the extent of the abnormality. A pressure sensor is connected to a dispensing flow passage system, including a sample probe and a dispensing syringe, and a plurality of output values of the pressure sensor during the sample dispensing operation are taken in. A multi-item analysis (based on the Mahalanobis distance) is carried out by using, as items, the plurality of taken-in output values of the pressure sensor. Whether the dispensing is normally performed or not is determined by comparing an analysis result with a threshold. A highly reliable determination result is obtained in spite of variations of sensitivity of the pressure sensor.</p> |
