Abstract: A method of correcting mass spectral data comprises making calibration measurements of first intrinsic components (A, B, C) at one or more calibration times (t1) using calibrants which have known mass to charge ratio (m/z) values or previously mass measured mass to charge ratio (m/z) values, making a list of second intrinsic components (D, E, F) which are present during more than one acquisition periods, wherein the second intrinsic components have mass to charge ratio (m/z) values that were not present or observed during or close to the one or more calibration times (t1) but which do overlap in time with the first intrinsic components (A, B, C), and utilising the list to calculate a mass or mass to charge ratio (m/z) correction factor for one or more acquisition periods which are not close or adjacent in time to an acquisition period containing a directly calibrated mass to charge ratio (m/z) value.

Abstract: A method of mass spectrometry is disclosed comprising passing ions to an oversampled Time of Flight mass analyser (4) and sequentially recording ion signals on a plurality of different channels (51, 52) to obtain a plurality of first oversampled mass spectral data sets of reduced complexity. An upstream separation device (3) may be provided to further reduce the complexity of each of the mass spectral data sets.

Abstract: Information regarding the operating conditions of a computer system is stored in a storage which is dedicated to a failure management system. The storage is updated with the current operating conditions either periodically or upon the occurrence of predetermined events. When a first failure identification mechanism identifies a failure in the computer system, a capture mechanism interrupts the updating of the storage leaving information regarding operating conditions which contributed to the failure in the storage. This latter information can then be read out to aid in diagnosis of the failure. Since the operating condition information is stored in a dedicated storage, the information is not modified by events that take place after the failure is identified. In accordance with one embodiment, the computer system ordinarily holds state and other operating information in a set of storage devices, such as, for example, state registers.
