Abstract: An ionization device includes a first electrode comprising a conductive member coated with a dielectric layer. The ionization device also includes a spine extending adjacent to and at least partially along the first electrode. The ionization device further includes a second electrode comprising conductive segments disposed adjacent the first electrode. Each one of the conductive segments contacts the spine at a respective contact location. The dielectric layer of the first electrode separates the conductive member of the first electrode from the spine and the second electrode. The ionization device is configured to create plasma generating locations corresponding to respective crossings of the first electrode and the second electrode.

Abstract: A cartridge assembly includes a body portion (14), that is thermally and electrically non-conductive, defining an opening (28), a bus bar (18) coupled to the body portion, the bus bar being thermally and electrically conductive, and a clamping bar (20), including a scalloped surface configured to oppose the bus bar, the clamping bar being thermally and electrically conductive. At least one of the bus bar and the clamping bar is biased toward the other of the bus bar and the clamping bar.

Abstract: A mounting bracket is provided for mounting a vacuum pump to a spectrometer. The vacuum pump has a mounting flange, with a locking rib thereon. The mounting bracket has a body and a grip. The body has a locking flange shaped to engage the locking rib, a means for fastening the body to the spectrometer, and a grip biasing surface. The grip has a pump engagement surface for engaging the vacuum pump, and a guide surface for engaging the grip biasing surface.

Abstract: A plastic frame assembly for bearing weight and a method of assembling same, comprising a plastic support member having a bottom portion and a top portion. The bottom portion has a channel, a plastic-affiliating migratory securing adhesive, and a flexible porous membrane. The plastic affiliating migratory securing adhesive is applied to the channel and the flexible porous membrane is positioned on top of the channel and forced into the channel. The plastic affiliating migratory securing adhesive migrates through the flexible porous membrane and secures the flexible porous membrane to the bottom portion of the plastic support member. The top portion of the plastic support member may register with the bottom portion in such a way so that the flexible porous membrane is held in place only by the plastic affiliating migratory securing adhesive.
