摘要： PURPOSE:To concurrently measure many samples without mutual interferences by providing a bulkhead to fit multiple different measurement samples concurrently and distinctively to a sample hold section and providing a means to radiate primary ions or neutral particles to the samples individually. CONSTITUTION:A bulkhead 11 forming sample separation grooves is provided on a sample hold section 12 and samples 13-16 of four types, for example, are fitted while preventing interferences each other. Primary ions or neutral particles are applied to a deflection electrode 5 through a lens, and a deflection electrode control device varies the voltage of the electrode 5 to radiate the samples 13-16 of the hold section 12 in sequence continuously or selectively. The hold section is supported by a sample hold section support mount 18, and the position of the hold section 12 is controlled by controlling a shift bar 20. Accordingly, samples of many types can be concurrently measured without generating interferences among the samples.

摘要： PURPOSE:To make it possible to enhance the dynamic range of ion detection, by storing the relation of a gain and the reference signal of high applied voltage by preliminarily calculating the same from the relation of the change of specific peak intensity and the reference signal at the change time prior to measurement. CONSTITUTION:High voltage is applied to a secondary electron multiplier 1 from a high voltage power source 2 and a digital signal sent out from a computer control part 6 is sent to the power source 2 through a D/A converter 3. The output current of the multiplier 1 is subjected to voltage conversion by a current detector 4 to be sent to the control part 6 while digitized by an A/D converter 5. When the detection current of the detector 4 exceeds 10 A, the output of an amplifier 5 is saturated and the input value of the D/A converter 3 is reduced. A means for investigating the changing behavior of the output of the A/D converter 5 by the input value of the D/A converter 3 is provided. The obtained calculation value from this result is stored in memory to make it possible to easily and accurately enhance the dynamic range of ion detection.

摘要： PURPOSE:To improve the operability of a monitor by switching at a given interval of period and putting mass spectrum signal and mass marker signal into a displayer. CONSTITUTION:By a signal from the scanning signal generator 15 taking part in the scanning and stoppage of magnetic field, the coil current controller 14 sends a scanning current corresponding to a range of mass number to the magnet coil 11. The peak mass number, obtained by the scanning of magnetic field, is obtained by the peak detector 12, and then sent through the magnetic field detector 13 to the marker generator 16, where a calculation is made according to a basic equation for mass number and a marker is generated each time the mass number is varied. The output of the marker generator 16 and the output of the peak detector 12 are switched for every scanning of magnetic field and then put in the vertical axle controlling circuit 21.

摘要： PURPOSE:To curtail the queuing time when measuring the specimen by magnetic field repetitive sweeping to measure promptly, by connecting transistor elements in series, and raising the clamp voltage of counter electromotive voltage generated in the magnet. CONSTITUTION:By the repetitive sweeping of the magnetic field with the magnet current control circuit having transistors Q6 to Q11 connected in series, the counter electromotive voltage generated in the magnet is applied between the collector of transistor Q6 and the emitter of transistor Q11 by way of a magnet power source 1. Therefore, voltage is applied between resistors R6 and R11, so that the resistors R6 to R11 are capable of not only determining the base potential of transistors Q6 to Q11, but clamping the voltage when a counter elecrromotive voltage is applied. Thus, it is possible to raise the clamp voltage, hence the returning time of the magnetic field may be curtailed.

摘要： PURPOSE:To increase denitration efficiency by injecting NH3 and aq. H2O2 soln. of low concn. into NOx-contg. gas. CONSTITUTION:Into NOx-contg. gas is injected spray of NH3 and aq. H2O2 soln. of concn. not higher than 30wt%, pref. not higher than 10wt%, or more pref. not higher than 3wt%. The lower the concn. of the aq. H2O2 soln. is, the less is the formation of NO2 because no local, high H2O2 concn. zone is formed. The formation of NO2 inhibits the denitration due to the reaction of NO with NH3. Addn. of H2O2 causes the noncatalytic denitration to processed even at a low temp. region, with increase in denitration efficiency for combustion gas.
