摘要： The invention provides an ion mobility analyzer apparatus and analysis method. The analyzer apparatus includes an ion source, two groups of parallel electrodes, a power supply unit and a detector. The drift region is formed between the two groups of parallel electrodes, and has an ion entrance connected to the ion source and an ion exit. Each group of parallel electrodes is located in a plane respectively, and the two planes are parallel to each other. The power supply unit is configured to apply direct current potentials on the two groups of parallel electrodes to form a direct current electric field that applies an opposing force on ions against the gas flow so that ions with different mobilities are trapped under the combined effect of the gas flow and the direct current electric field. The detector is connected to the ion exit to detect ions.

摘要： A linear ion beam bonding apparatus and an array structure thereof, comprising a pair of primary radiofrequency electrodes (501 and 502) extending along the axial direction and oppositely arranged on two sides of the central axis of the linear ion beam bonding apparatus. Section patterns on different section planes of each of the primary radiofrequency electrodes (501 and 502) and perpendicular to the central axis are all kept symmetric via a primary symmetric plane (506) of the central axis. Radiofrequency voltages attached to the primary radiofrequency electrodes (501 and 502) are of identical phases. An ion extraction groove (84) is arranged on at least one of the primary radiofrequency electrodes (501 and 502), while at least one pair of auxiliary electrodes (503 and 505) are arranged on two sides of the pair of primary radiofrequency electrodes (501 and 502). The auxiliary electrodes (503 and 505) are arranged in duality to the primary symmetric plane (506). At least one of the auxiliary electrodes (503 and 505) is provided with a finite number of symmetric planes (507), while a minimal angle greater than 0 degrees and less than 90 degrees is provided between each symmetric plane (507) and the symmetric plane (506) of the primary radiofrequency electrodes (501 and 502). By means of this, a quadrupole field component of an ion beam bonding radiofrequency electric field within the ion beam bonding apparatus is strengthened.

摘要： The invention provides ion mobility analyzer and analysis method. The analyzer includes an ion source, a first drift/analyzer region provided with an ions entrance, a second drift/analyzer region provided with an ions exit, a connection region connecting the first drift/analyzer region and the second drift/analyzer region, and a detector connected to the ion exit. Direct current electric fields and gas flows in the first drift/analyzer region and the second drift/analyzer region apply opposing forces on ions, and first and second gas flows have the same gas flow direction. The connection region includes a third direct current electric field that causes ions to transfer from the first drift/analyzer region to the second drift/analyzer region. Because the first and second regions have the same gas flow direction, the invention achieves stable resolution and sensitivity as a high-resolution ion mobility analyzer and/or an ion mobility filter for a continuous ion beam.
