摘要： A light beam emitted by a hollow cathode lamp is concentrated on a central portion of an electrothermal sample atomizing apparatus by a concave mirror. The light concentrated on the central portion of the electrothermal sample atomizing apparatus is further concentrated on a central portion of a flame produced in a burner type sample atomizing apparatus by a lens. The light traveled through the burner type sample atomizing apparatus is condensed by a concave mirror, reflected by a flat mirror, and concentrated on an entrance slit of a spectroscope.

摘要： The invention intends to provide an atomic absorption spectrophotometer which can establish a uniform heat distribution during heating of a sample and can improve analysis accuracy and analyzing efficiency. For this purpose, a graphite tube type cuvette mounted in a graphite atomizer furnace for an atomic absorption spectrophotometer comprises a large-diameter portion for retaining a sample in place, a small-diameter portion connected to the large-diameter portion and having a smaller diameter than the large-diameter portion, and a step portion for demarcating between the large-diameter portion and the small-diameter portion. The graphite tube type cuvette is formed such that its cross-sectional area in a plane perpendicular to the direction of passage of an electric current supplied to the cuvette is the same in any of the large-diameter portion, the small-diameter portion and the step portion. The amount of resistance heat is thereby also the same in any portions.

摘要： Performing an MS3 with a tandem mass spectrometer causes problems of increase in size of the device and of increase in cost. Likewise, a plural number of times MS/MS analyses are even more difficult. An electrode to create a harmonic potential is disposed in a collision cell, and fragment ions produced by the first-time collision induced dissociation are accumulated in the harmonic potential. Target ions of the subsequent stage are let out, by means of an axial resonance excitation, selectively from the accumulated ions. The ions are excited in the axial direction to have a potential exceeding the harmonic potential. Thereby, the second-time collision induced dissociation is performed by means of a potential difference provided at the subsequent stage. In addition, an operation to return the ions back to the harmonic potential enables a plural number of times MS/MS analyses to be performed.

摘要： The present invention provides a tandem type mass analysis system capable of carrying out the differential analysis with high efficiency by the tandem type mass analysis. A predetermined number of m/z regions are set up for carrying out the mass analysis with the all ions included therein being dissociated collectively for each m/z region so as to obtain measurement MS2 data. By comparing the measurement MS2 data with reference MS2 data stored in a reference data base, a difference thereof is detected. For the m/z region with a differential component detected, the mass analysis is carried out collectively without dissociation for the all ions included therein so as to obtain measurement MS1 data. By comparing the measurement MS1 data with the reference MS1 data, a difference thereof is detected. From the difference thereof, a parent ion considered to be the differential component factor is presumed for carrying out the mass analysis with the same being dissociated.

摘要： An “ion trap-TOF/MS” capable of calibrating the observed mass for each of an ion trap and a TOF. In the ion trap-TOF/MS, sample ions having known mass numbers and ionized by an ion source are trapped within an ion trap. Auxiliary AC voltages having a frequency component ω are applied to the end cap electrodes of the ion trap to expel unwanted ions out of the ion trap. A measurement process is carried out by applying DC voltages to the ring electrode and the end cap electrodes to expel an ion remaining within the ion trap, and measuring the mass number of the expelled ion by the time-of-flight mass spectrometer. The measurement process is repeated while changing the frequency component ω, and the ion signal intensity measured by the time-of-flight mass spectrometer is compared with a previously stored threshold, thereby making calibration of the frequency component ω for the ion having the known mass number. Thus, the calibrating of the observed mass can be realized for each of the ion trap and the TOF.
