Abstract

See full text

A sample apparatus includes a sampling valve having a sample inlet through which a sample such as urine is introduced from the outside of the sampling valve to the inside thereof; a sample outlet through which the sample is sent from the inside of the sampling valve to the outside thereof; and a sampling passage for setting apart a predetermined amount of the sample between the sample inlet and sample outlet. It further includes a first electrode section located close to the sample inlet so that the sample can come into contact with the first electrode section, a second electrode section located close to the sample outlet so that the sample can come into contact with the second electrode section, and a sensor circuit for measuring the impedance between the first and second electrode sections and for using the measured impedance to determine whether or not the sampling passage contains a predetermined amount of the sample. Preferably, the first and second electrode sections each include a pair of electrodes separated from each other, wherein one of each of the electrodes of the electrode sections is connected to the sensor circuit while the other electrodes are short-circuited to each other.
