摘要： A miniature multipole rod assembly which can be operated as an ion guide or a mass analyzer is constructed by bonding individual rods directly to plates which are separated by ceramic insulators. The multipole rod assemblies are constructed by using a fixture which locates and orients all elements during the process or bonding the rods to the disks.

摘要： An Atmospheric Pressure Ion (API) source is configured for Electrospray (ES) and Atmospheric Pressure Chemical Ionization (APCI) operating modes. The API source includes a multipurpose heater assembly mounted in the API source chamber. The multipurpose heater supplies heat to the API chamber endplate, bath gas and entrance end of the capillary orifice into vacuum as well as supplying electrical connections to the API source elements. An additional heater is configured at the exit end of the capillary orifice into vacuum. With this configuration, the bath gas, endplate and capillary entrance temperature can be set independent of gas flow rate. The capillary exit and entrance temperatures can be set independently as well. The multipurpose endplate heater combined with the capillary exit heater allows the optimization of API source performance over a wide range of operating conditions and analytical applications.

摘要： Improvements have been made to the Electrospray and Atmospheric Pressure Chemical Ionization source chambers interfaced to mass spectrometers to simplify source performance optimization and source operation and to improve system sensitivity. The atmospheric pressure ion source procedure for optimizing performance has been simplified by adding windows along the sides of the atmospheric pressure ionization chamber allowing direct viewing of the Electrospray and Atmospheric pressure ion sources during operation. A cylindrical lens which extends along the side walls of the atmospheric pressure chamber has been configured to be semitransparent for viewing into the chamber. This cylindrical shaped side lens is electrically isolated from the Electrospray liquid introduction needle and Electrospray chamber endplate. Improved Electrospray mass spectrometer system sensitivity can be achieved when operating the cylindrical lens with a higher potential difference between it and the Electrospray liquid introduction needle than is set between the needle and the endplate.

摘要翻译： 已经对与质谱仪连接的电喷雾和大气压化学电离源室进行了改进，以简化源性能优化和源操作，并提高系统灵敏度。 通过在大气压电离室的侧面添加窗口可简化用于优化性能的大气压离子源程序，从而可以在运行期间直接观察电喷雾和大气压离子源。 沿着大气压力室的侧壁延伸的圆柱形透镜已经被配置为半透明的，用于观察室。 该圆柱形侧透镜与电喷雾液引入针和电喷雾室终板电隔离。 当操作具有比电针与终板之间设置的电喷雾引入针之间更高的电位差的柱面透镜时，可以实现改进的电喷雾质谱系统灵敏度。

摘要： An API source for mass spectrometry which is configured such that all or a portion of its vacuum assembly, including ion focusing and transport electrostatic lenses and ion guides, and two or more vacuum stages can be removed from the source or system vacuum housing as a complete assembly. The API source may be an ES, APCI or ICP source, or any other ion source which operates at substantially atmospheric pressure. The insert assembly can be electrically isolated from the grounded vacuum housing to enable the delivery of kilovolt potential ions into a magnetic sector mass analyzer from the API source. The insert assemblies can be configured to interface to quadrupole, Time-Of-Flight, ion trap, Fourier Transform, and magnetic sector mass analyzers. Electrical connections can be configured internally to make and break automatically when said insert assembly is inserted or removed from the surrounding vacuum housing. The insert assembly is configured to be removed from the vacuum housing without the need to disconnect vacuum pumps, vacuum pumping lines, vacuum gauges, or external electrical connectors. The invention simplifies the cleaning and maintenance of API mass analyzer systems, can reduce the cost and complexity of said systems and can reduce instrument down time. The API insert assembly removal allows for the insertion of alternative ion sources, for example, Laser Desorption, Electron Bombardment, Chemical Ionization, Thermospray, and Particle Beam hardware which can utilize the same vacuum pumps and electrical contacts as are used by the API source.
