Abstract: A vapour generator system (1, 101) for an IMS (4, 104) or other apparatus has a chamber (9, 109) in which vapour is produced. A fan or other flow generator (6, 106) is connected to an inlet (8, 108) of the vapour chamber (9, 109) and its outlet (13, 113) is connected to an adsorbent passage (14, 114), such as formed by a bore through a block (15) of carbon. When the fan (6, 106) is on gas flows through the vapour chamber (9, 109) and the adsorbent passage (14, 114) to the IMS (4, 104) or other outlet, with little vapour being adsorbed in the passage. When the fan (6, 106) is off, any vapour molecules that escape to the adsorbent passage (14, 114) do so at a low rate such that substantially all is adsorbed and no vapour escapes.

Abstract: An ion mobility spectrometer has a pair of electrodes (13A) and (13B) midway along the drift chamber (7). A high field is applied between the electrodes (13A) and (13B) sufficient to modify (e.g. fragment) ions in the region of the electrodes such that they move at a different rate towards the collector plate (8) . This is used to modify the time of flight of selected ions or ion clusters and enable identification of ambiguous peaks on the IMS spectrum.
Abstract translation: 离子迁移谱仪在漂移室（7）的中途具有一对电极（13A）和（13B）。 在电极（13A）和（13B）之间施加足以在电极区域中修饰（例如片段）离子的高场，使得它们以不同的速率朝向集电板（8）移动。 这用于修改所选择的离子或离子簇的飞行时间，并使得能够识别IMS谱上的模糊峰。

Abstract: An ion mobility spectrometer has two drift chambers and a common, doped reaction region. Each drift chamber includes an ion modifier, such as one that fragments the doped ions by a high electrical field. One of the drift chambers is doped and the other is undoped. In this way, the dopant adducts are removed by the modification process but then recombine with dopant only in the doped chamber so that different outputs are produced by the two drift chambers.

Abstract: An IMS system or the like has dopant contained in a way such that it is only released when needed. The dopant could be contained in a device (50) similar to an ink-jet printer and released as droplets (55) when required. Alternatively, the dopant could be trapped in material (156) of a molecular sieve (150) in such a way that it is not normally released into air flowing through the sieve but can be released by energizing a heater (157) in the sieve.
Abstract translation: IMS系统等以掺杂剂的方式使其仅在需要时被释放。 掺杂剂可以包含在类似于喷墨打印机的装置（50）中，并且当需要时作为液滴（55）释放。 或者，掺杂剂可以被捕获在分子筛（150）的材料（156）中，使得其通常不被释放到流过筛子的空气中，但是可以通过向筛中的加热器（157）通电而释放。

Abstract: An ion mobility spectrometer has a reaction region separated from a drift region by an electrostatic gate. A doping circuit supplies a dopant to the reaction region but the drift region is undoped. Two high field ion modifiers are located one after the other in the drift region. One ion modifier can be turned on to remove dopant adducts from the admitted ions, or both ion modifiers can be turned on so that the ions are also fragmented. In this way, several different responses can be produced to provide additional information about the nature of the analyte substance and distinguish it from interferents.

Abstract: An ion mobility spectrometer or other ion apparatus has two or three grid electrodes 51 and 52; 151 to 153; 106 and 107; 106′ and 107′ extending laterally of the ion flowpath. An asymmetric waveform with a dc compensating voltage is applied between the electrodes to produce a field parallel to the ion flow path that affects ions differently according to their field-dependent mobility. This filters or delays different ions selectively in their passage to an ion detector 11, 111, 111′ to facilitate discrimination between ions that would otherwise produce a similar output.
