DETECTOR FOR SAMPLE TO BE MEASURED AND AUTOMATIC CHEMICAL ANALYZER USING THE SAME

摘要

PURPOSE: To enable the detecting of a correct amount of a liquid even when a trace of a sample to be measured is in a sample container and even for various sample containers with the shape thereof differing from one another. ;CONSTITUTION: This apparatus is constituted of a capacity detecting section 3 which is provided with a probe 1 comprising a conductive member and allowed to contact a sample to be measured housed into a sample container and a bridge circuit 9 connected to the probe 1 to detect changes in electric capacity corresponding to the amount of the sample to be measured with the probe 1 contacting the sample to be measured by a phase detection method and a amount of the sample calculating section 7 to calculate the amount of the sample to be measured based on the electric capacity detected by the capacity detecting section 3.;COPYRIGHT: (C)1996,JPO
