Abstract:
1. A liquid sample analyzer comprising: a dispensing part comprising an aspiration tube having an aspiration orifice near a tip thereof for aspirating a liquid sample to be analyzed; a mixing part comprising a chamber; a detecting part comprising a light source and a light-receiving device facing the light source; an analyzing part; and a computer processor configured to: cause the dispensing part to dispense a first collected material in a first region of the aspiration tube and a second collected material in a second region of the aspiration tube between the first region and the tip and to discharge the second collected material to the chamber of the mixing part; cause the mixing to part to prepare a mixed sample by mixing reagent and the discharged first collected material supplied from the first region of the aspiration tube; cause the detecting part to irradiate the second collected material with the light source, obtain optical information associated with the second collected material at the light-receiving device, and detect a presence of the liquid sample to be analyzed in the dispensing part based on the optical information associated with the second collected material; and cause the analyzing part to perform a measurement of the mixed sample; and further cause the mixing part to fail to prepare the mixed sample so that the analyzing part fails to perform the measurement, when the detecting part fails to detect the presence of the liquid sample to be analyzed.
