Abstract: The present invention provides a probe apparatus and method as described below for use as a non-destructive testing (NDT) device to detect and locate structural flaws in a composite laminate. In preferred embodiments, the method includes measuring effective thermal conductivity (Ke) of the laminate using one contact surface, non-invasively. The device is preferably portable and battery-operated. The thermal conductivity method on which the device is based is much simpler to use than the known devices for NDT and allows the utilization of a direct correlation between thermal conductivity and mechanical strength in the case of polymer composites. The device may also be used for process control in manufacturing and monitoring materials in service.

Abstract: An Atmospheric Pressure Chemical Ionisation (“APCI”) ion source is disclosed comprising a housing 14 having a corona discharge chamber 1, a reaction chamber 2 and a passage 6 connecting the corona discharge chamber 1 to the reaction chamber 2. Reagent ions are formed in the corona discharge chamber 1 and pass to the reaction chamber 2 via the passage 6. Analyte is sprayed into a heated tube 3. Low to moderately polar analyte molecules pass from the heated tube 3 into the reaction chamber 2 whereupon the analyte molecules are ionised by interacting with reagent ions. In contrast, highly polar analytes are ionised by thermal ionisation processes within the heated tube 3 and hence highly polar analyte ions pass into the reaction chamber 2. Analyte ions entering the reaction chamber 2 are substantially shielded from the effects of an electric field generated in the corona discharge chamber 1 as part of the process of generating reagent ions.

Abstract: A magnetic sector mass spectrometer is disclosed comprising an ion detector (11) wherein a reflecting electrode (13) is used to divide an ion beam in the direction of mass dispersion into two separate ion beams. The two ion beams are directed onto two detectors which preferably comprise two or more conversion dynodes (15a, 15b) and two or more corresponding microchannel plate detectors (14a, 14b) to detect electrons produced by the conversion dynodes (15a, 15b). If the signal from the two detectors differs substantially then the ion beam can be determined to include interference ions. Conversely, if the signal from the two detectors is substantially the same then the ion beam can be determined to be substantially free from interference ions.

Abstract: A method of mass spectrometry is disclosed wherein a collision, fragmentation or reaction device is repeatedly switched between a high fragmentation or reaction mode and a low fragmentation or reaction mode. Parent ions from a first sample are passed through the device and parent ion mass spectra and fragmentation ion mass spectra are obtained. Parent ions from a second sample are then passed through the device and a second set of parent ion mass spectra and fragmentation ion mass spectra are obtained. The mass spectra are then compared and if either certain parent ions or certain fragmentation ions in the two samples are expressed differently then further analysis is performed to seek to identify the ions which are expressed differently in the two different samples.

The effect of trapping the ions according to a preferred embodiment is that singly charged ions which may, for example, comprise unwanted background ions are substantially lost from the trap whereas multiply charged analyte ions are maintained within the ion trap and can then be released for subsequent mass analysis.

Abstract: A mass spectrometer is disclosed comprising an ion source 4, a field free or drift region 5 and an ion mirror 7 comprising a reflectron. Metastable parent ions which spontaneously fragment by Post Source Decay whilst passing through the field free or drift region 5 are arranged to enter the ion mirror 7 and be reflected by the reflectron towards an ion detector 8 when the reflectron is maintained at a certain voltage. The process is then repeated with the reflectron being maintained at a slightly lower voltage. Two related sets of time of flight or mass spectral data are obtained for the two different voltage settings of the reflectron. From the two data sets the different times of flight for the same species of fragment ion can be determined. The mass to charge ratio of the parent ion which fragmented to produce the particular species of fragment ion can then be determined from the times of flight of the fragment ions.

By accurately determining the error band the possible candidate ions in a database can be accurately restricted whilst also guarding against over restriction.
