Abstract: Provided is an automatic analysis device that can suppress concentration of a reagent made to react with a specimen. This automatic analysis device is provided with: a reagent container which accommodates a reagent and which has attached thereto a perforable lid; a perforation unit for perforating the lid; and a reagent suction nozzle that is inserted into a hole formed by perforation and that sucks up the reagent. The automatic analysis device is characterized by being further provided with a state storage unit that stores the state as to whether the reagent container is in an unused state or in a used state, and a state update unit that, when the lid is perforated by the perforation unit while the reagent container is in an unused state, updates the state stored in the state storage unit to the used state.

Abstract: Linearization of an ionization detector is obtained by processing the output signal derived from the ionization detector so as to compensate for the naturally-occurring logarithmic decay of the detector response at high sample concentrations. Linearization is accomplished according to a linearizing formula:I.sub.(lin) =I[1+(I/I.sub.(dec))].sup.pwrwhere:I.sub.(lin) =linearized output signal current of the detectorI=non-linearized output signal current of the detectorI.sub.(dec) =output signal current at onset of logarithmic decaypwr=a power factor that compensates for the slope of the logarithmic decay

Abstract: An electron capture detector has a detection cell containing an electrode and a radioactive isotope for ionizing a carrier gas and causing electrons to be emitted. Before the detection cell begins to be contaminated, a pulse voltage is applied to the electrode and the frequency of this pulse voltage is controlled by a loop control routine to find an initial pulse frequency value such that a current through the electrode due to the emitted electrons comes to have a specified current value as a carrier gas is introduced into the detection cell. When a sample is analyzed after the detection cell becomes contaminated, the same process is carried out before the sample is injected and a pre-measurement pulse frequency value is obtained. After the sample is injected, the same process is repeated to obtain a measured pulse frequency value. The concentrations of components of the sample are calculated from the measured pulsed frequency value, and the effects of contamination of the detection cell are removed by considering both the initial and pre-measurement pulse frequency values.
