摘要： In a discharge ionization detector, a method and apparatus are disclosed for increasing the transfer of photons and metastables from a discharge chamber to a ionization chamber, while effecting ion discrimination of the ionic current with respect to a signal cathode, thereby reducing the effect of ionic current in the signal output. Preferred embodiments of the invention include a discharge source located in a discharge chamber, means for introducing discharge gas flow into the discharge chamber, a flow guide that directs discharge gas flow between the discharge chamber and an adjacent ionization chamber, and inlet port for introducing a flow of sample gas containing an analyte into the ionization chamber and an outlet port for exhausting the sample gas and the discharge gas. A plurality of apertures in the flow guide are situated proximate the discharge source so as to promote the rapid and efficient transfer of photons and metastables from the discharge source into the ionization chamber. A signal cathode and the ionization chamber are biased in a circuit with an electrometer so as to provide a detector output signal.

摘要： An apparatus is provided to facilitate the transfer of baggage on conveyor systems at the junction between a sort conveyor and a take-away conveyor. The transfer apparatus includes a sweeper arm that rotates across the sort conveyor to sweep a baggage article thereon toward the take-away conveyor. The sweeper arm translates linearly relative to the sort conveyor so that the baggage remains in continuous contact with the sweeper arm. The rotation of the arm is coordinated with the translation so that the baggage will be fully diverted from the sort conveyor by the time the sweeper arm reaches the end of its translation.

摘要： An airflow director constructed for use with a separation column in a temperature-controlled air bath in a chromatographic oven cavity, wherein the airflow director includes at least a first baffle locatable with respect to the separation column and to the low pressure and high-pressure regions of the air bath, wherein the baffle is configured to direct air flow away from the high-pressure region before passing over the separation column. The temperature-controlled air thereby mixes with oven cavity air before passing over the separation column, which is thereby less subject to thermal gradients.

摘要： An inlet liner is provided for use in an inlet assembly of a chromatograph system. The inlet liner has an elongate tube that extends along a longitudinal axis and defines a bore that extends along the longitudinal axis and has an inner bore surface. At least one projection extends from the inner bore surface into the bore. Chromatograph systems are provided including the exemplary inlet liner(s). Methods are also provided for analyzing a sample containing a matrix in a chromatograph system having an inlet assembly connected to a chromatograph column. The method includes positioning an exemplary inlet liner in the inlet assembly, flowing the sample through the inlet liner, and adhering a portion of the matrix to a projection surface of at least one projection of the inlet liner.

摘要： A blow molded container for liquids is vertically stackable with geometrically similar containers. Each container has a unitary body formed of an extruded parison the thermoplastic material. The containers have a bottom surface which includes a release groove bifurcating the bottom surface, the release groove including a remnant portion of the parison forming a web-like external rib depending downward within the release groove. A top surface of the container includes an opening closed by the cap and includes a notch which receives the remnant portion of the parison of a geometrically similar container stacked thereon to laterally locate and stabilize the relative positions of the stacked containers.
