Title: Ion source for a mass analyser and method of cleaning an ion source
Inventor: BAJIC STEVAN
IPC: H01J49/04
Filed: 1998-08-06
Granted: 2006-02-21
Abstract: An ion source for a low pressure mass spectrometer has an atmospheric pressure sample ioniser operative at relatively higher pressure to provide a sample flow containing desired sample ions to the mass spectrometer via an inlet orifice. The sample flow invariably contains involatile components that are infused either as chromatographic buffers or which appear in the analyte as sample extraction byproducts. As the sample ions pass from the high pressure to the low pressure, regions through the orifice, these involatile components are deposited on the peripheral regions of the inlet orifice. A conduit for the transportation of a cleaning fluid has an opening adjacent to the inlet orifice for dispensing the cleaning fluid onto at least a portion of a surface of the orifice member during operation of the ion source.

Abstract: An annular heat exchanger (2) provided with a high temperature fluid passage inlet (11) at one end in the axial direction and a low temperature fluid passage inlet (15) at the other end in the axial direction is supported inside a cylindrical outer casing (9) via a heat exchanger supporting ring (36). The heat exchanger supporting ring (36) connecting a low temperature section near the low temperature fluid passage inlet (15) of the heat exchanger (2) and a posterior flange (33) of the outer casing (9) is formed by bending a sheet in a cross-sectionally step shape so that it can readily undergo elastic deformation to offset the thermal expansion of the heat exchanger (2). This ensures positive sealing between the high temperature fluid passage inlet (11) and the low temperature fluid passage inlet (15) of the heat exchanger (2) while minimizing the thermal stress occurring in the heat exchanger (2) and the outer casing (9). The heat exchanger supporting ring (36) also has a function of partitioning between a combustion gas passage inlet (11) and an air passage inlet (15).

Abstract: The invention relates to a method for reducing the formation of clods and the clustering tendency of reducible iron-containing agglomerated material, particularly so-called pellets, whereby the reducible iron-containing agglomerated material, following a desulphurisation process that takes place after a sintering process during the manufacture of the said pellets, is given an outer layer of clustering-reducing material in the form of a liquid suspension of particulate material. According to the invention, a more even distribution of the coating on the surface of the agglomerate is achieved in that the application of the liquid suspension takes place during tumbling in a drum that is designed so that the agglomerate together with the liquid suspension can essentially pass freely through it.

Abstract: The invention provides a system for assaying protein-protein interactions. Amino acid sequences of interest are inserted into 'bait" and "prey" fusion proteins. The bait fusion proteins include a DNA-binding domain.  The prey fusion proteins include a transcriptional repression domain. The interaction of the bait and prey fusion proteins is detected by the repression of reporter genes. The reporter genes have operator sequences to which the DNA-binding domain of the bait fusion protein can bind. The reporter genes are expressed unless the prey fusion protein interacts with a bait fusion protein at the operator region of the reporter gene. When a prey fusion protein binds to a bait fusion protein, the expression of the reporter gene is repressed. Compounds that interfere with the interaction of bait and prey fusion proteins may be detected by their ability to reverse the repression of the reporter genes.
