摘要： The invention concerns a graphics display system of the kind having a refresh raster display device, a line clipping mechanism for clipping line primitives for viewing in a selected rectangular viewport having horizontal and vertical edges parallel to the X and Y axes respectively of the display area of the display device, and a vector-to-raster converter for converting the clipped lines to patterns of discrete pels in a refresh buffer, the vector-to-raster converter including an incremental line drawing mechanism responsive to line information supplied by the clipping mechanism to draw the line starting at one endpoint and proceeding towards the other. In such a system, for at least some lines of a kind which have a first endpoint in the viewport and the second endpoint outside the viewport, the clipping mechanism is arranged to avoid calculating the intersection point of the line with the viewport edge intersected by the line, and the vector-to-raster converter is arranged to start the line drawing mechanism at the first endpoint and halt the line drawing mechanism when the currently generated coordinate along the display axis normal th the said viewport edge equals the coordinate of the viewport edge along the same axis.

摘要： A gas chromatography system includes a gas chromatography oven having a door adapted for integration with gas chromatography modules which are located outside of the oven cavity. For these purposes, the oven door has module receiving openings in which the modules are secured. The gas chromatography module includes a module housing containing a main coil of the capillary column, a pair of transfer lines sleeved on the free ends of the capillary column, a heater wire wound on the transfer lines, and, optionally, a pair of chromatography connectors which extend into the oven cavity and through which the free ends of the capillary column, as well as transfer lines, projecting into the oven cavity. A wall of the GC oven has an injector port and a detector port for injection of a sample into the oven cavity and for detecting the sample constituents. Column lengths extend within the oven cavity between the module and injector and detector, respectively. An electronic control block is positioned outside the oven cavity and mounted on the door in proximity to the modules to control the heating of the transfer line of the module.

摘要： A system for analysis of vapor constituents in a gaseous and/or liquid media includes an analyzing gas chromatographic unit, an in-line preconcentrator assembly having a trap housing, an adsorbent material received in the trap housing, and a transfer line unit couplable to the trap housing and directly connected to the analyzing unit. Carrier mechanism drives the trap housing with respect to the transfer line unit linearly or along an arc trajectory. When the trap housing is displaced from the transfer line unit, the media surrounding the trap housing is forced inside of the trap housing by a pump and vapor constituents are adsorbed on the adsorbent material within the trap housing. When the trap housing is moved in pressure tight engagement with the transfer line unit, the adsorbent material is heated to release the vapor constituents from the adsorbent material.
