Abstract: The present invention provides a flame atomic absorption spectrophotometer in which, when a flashback may occur, a continuous use of this apparatus through an easy operation by a user is prohibited, so that the apparatus cannot be used unless its safety is confirmed. In this apparatus, when a flashback occurrence detector 23 detects that a flashback has occurred while the flame was burning, it extinguishes the flame in accordance with a predetermined extinction sequence, sets a flashback occurrence flag to be “1,” and increments a flashback count value. Even if an ignition button 26 is pressed, an ignition is not allowed if the flashback occurrence flag is “1.” When a password that was issued after the safety was confirmed by the manufacturer is entered through an operation unit 41, a password verification unit 40 in a personal computer 4 obtains a flashback count value. If the reference password which corresponds to the flashback count value and the entered password match, an apparatus controller 20 resets the flashback occurrence flag to cancel the state where an ignition is inhibited. When the flashback count value becomes equal to or more than a predetermined value, the apparatus must be sent to the manufacturer with a request for examination and possible repair, since no reference password is available.

Abstract: The present invention has been accomplished to provide an atomic absorption spectrophotometer capable of obtaining measurement data always in the state where the lowest detection limit performance is optimized, without depending on the frequency of the power supply. In a control program which runs on the microcomputer chip 42 mounted on the atomic absorption spectrophotometer 110, a plurality of lighting periods of the light sources 11 and 12 and extraction periods of the sampling data are memorized, whose lowest detection limit performance are optimized for the frequencies (50 Hz and 60 Hz) of the AC power source for driving the AC motor 22. In using the apparatus, by the control program, the frequency of the power source used in this apparatus is identified, the lighting period and sampling data extraction period corresponding to the identified frequency and the measurement mode that a user of the apparatus has previously set are selected from among a plurality of memorized values, and the appropriate lighting period is set to the hardware (PLD 43). Accordingly, without depending on the frequency, it is possible to obtain measurement data always in the state where the lowest detection limit performance is optimized.

Abstract: A shift of mass axis that occurs when the temperature of a vacuum container consisting of a vacuum chamber (15) and IT block (16) or that of a TOF power unit (20) for applying an ion acceleration voltage is changed, is respectively measured beforehand, and parameters expressing a transfer function based on its response are stored in a transfer function memory (24). During an analysis, a mass shift predicting operation section (25) estimates the current shift length of the mass axis from the current temperatures of the IT block (16) and TOF power unit (20) obtained by first and second temperature sensors (34 and 35) as well as from the two transfer functions stored in the memory (24). A mass shift correcting section (29) corrects the mass axis of the mass spectrum according to the estimated shift length. Thus, if the ambient temperature suddenly changes, the shift of the mass axis of the mass spectrum due to the temperature change is corrected with high accuracy, so that a mass spectrum with a high level of mass accuracy can be created.
