摘要： An MS/MS-time-of-flight mass-spectrometer for colliding ions with the molecules or atoms of some collision gas. In order to assign the fragment ions to their respective parent ions, some ion selecting mechanism such as an ion gate must be used to preselect one specific mass of the primary ion spectrum. Usually the combination of both elements, a collision cell and an ion selector will need so much space that the size of the mass-spectrometer will increase, also reducing its sensitivity. This effect can be avoided, by integrating ion selector and collision cell into one unit.

摘要： A mass spectrometric analysis of the content of surfaces, it is necessary to bring the analyte molecules into the gas phase. This is done with a tightly focused, preferably pulsed laser beam. This laser beam is focused onto the surface with a mirror that is placed as close as possible to the analysed surface. In order to achieve a very small focal point, deflection and focusing of the laser beam is done with a single optical element. The evaporated material passes through a opening in the mirror into the mass spectrometer. It is also possible to let the evaporated material pass right next to the mirror into the mass spectrometer.

摘要： Driver for Pockels cells and using this Pockels cell within laser systemsThe driver i.e. the electrical control of the Pockels cell is modified from the standardly known H-configuration using the switches S1, S2A; S1A, S2 A by adding at least one more switch (S2B; S1B; S2B). This switch can either replace the usually used recharging resistors (R2) or can be placed to these in parallel. It is also possible to use an arrangement using 4 switches (S1A, S2A, S1B, S2B) and no recharging resistors at all. Using such a driver with a Pockels cell pulses can be selected in laser systems more efficiently. Pulse sequences with well defined widths and spacing can be produced for certain application.

摘要： In order to effect fragmentation of ions through collisions with gas-phase molecules, it is necessary to have a high gas pressure in the collision region. At the same time the residual gas pressure in the detector region of a mass-spectrometer must be kept low. This is done by arranging collision cell and detector into separately pumped vacuum regions, each region having its own pumping port, the regions only being connected via flow restrictions in the vicinity of the ion optical axis. Achieving large pressure gradients and at the same time not reducing the sensitivity of the mass spectrometer can be done by using gas flow restrictions with large cross sections. A very efficient and space saving arrangment is to place a separate chamber with the collision cell between the chamber housing the reflector and the detector and the chamber housing the ion source of the mass spectrometer.
摘要翻译： 为了通过与气相分子碰撞来实现离子的碎裂，必须在碰撞区域中具有高的气体压力。 同时，质谱仪检测器区域中的残留气体压力必须保持较低。 这是通过将碰撞池和检测器设置在单独的抽真空区域中，每个区域具有其自己的泵送端口，这些区域仅通过离子光轴附近的流动限制而连接。 实现大压力梯度，同时不降低质谱仪的灵敏度可以通过使用具有大截面的气流限制来实现。 非常有效和节省空间的布置是将容纳反射器的室与检测器和容纳质谱仪的离子源的室之间的碰撞池放置在单独的室中。
