A mass analysis of a standard sample having a known mass-to-charge ratio is carried out by performing a mass scan at a first-stage quadrupole (13) over a predetermined mass range, under the condition that a collision induced dissociation (CID) gas is introduced into a collision cell (14) and a voltage applied to a third-stage quadrupole (17) is set so that no substantial mass separation occurs in this quadrupole. Various kinds of product ions originating from a precursor ion selected by the first-stage quadrupole (13) arrive at and are detected by a detector (18) without being mass separated. Accordingly, based on the detection data, a data processor (25) can obtain a relationship between the voltage applied to the first-stage quadrupole (13) and the mass-to-charge ratio of the selected ions, with a time delay in the collision cell (14) reflected in that relationship. This relationship is stored in a calibration data memory (26), to be utilized in a neutral loss scan measurement or the like. By using this relationship, a mass shift due to the time delay in the collision cell (14) can be cancelled, so that the product ions can be detected with high sensitivity over the entire mass range. Furthermore, a mass spectrum having an accurate mass axis can be created.

Embodiments of the present invention provide methods and apparatus for decoding digital video or motion picture signals with error concealment to prevent or minimize degradation of the picture quality. When corruption occurs, the method determines whether error concealment is needed according to a preset criterion. If so, motion vectors for the corrupt region are calculated using the motion vectors and rates of change of motion of current blocks in the current frame and / or old blocks in a previous frame according to a best matching block selection process. The method also determines if the “time” relative motion of content is small by defining a percentage use parameter. In some cases, once the error concealment is complete, the “weight” or visual sensitivity of the restored block is decreased in order to reduce boundary artifact effects. This is accomplished by a quantization mask employing the human visual system (HVS) concept.
