摘要： A method is disclosed for the quantitative analysis of the contents, in nitrogen, of hydrogen and methane by means of ionic mobility spectrometry, consisting of a) performing a measurement of the apparent hydrogen concentration in the nitrogen under examination; b) performing a measurement of the apparent hydrogen concentration in a flow of the same sample of nitrogen, purified from all impurities but methane; and c) comparing the two measure. A system is also disclosed for carrying out the method.

摘要： A corona discharge ionisation source is disclosed in which neutral species are removed by directing a flow of oxygen containing gas in a direction substantially different to that of the ion flow. The ion profiles produced are similar in many respects to those produced by a 63Ni source, thus an alternative, non-radioactive, ion source is offered.

摘要： A method for eliminating interference when analyzing a test sample of a bulk inert gas in an ion mobility spectrometer is disclosed which includes the steps of providing an ionization source for the spectrometer to form ions of the bulk inert gas, mixing a reagent gas with the test sample prior to entry into the spectrometer to alter the nature of the ions formed by the bulk inert gas to shift the location of a bulk inert gas mobility peak such that a bulk inert gas mobility peak does not overlap with an impurity mobility peak of the ions of a trace impurity of interest, whereby bulk inert gas ions are quenched and a clusters of the reagent gas and the bulk gas are formed. Alternatively, the reagent gas may be mixed with the drift gas in the ion mobility spectrometer, rather than with the test sample.

摘要： A device for measuring a total concentration of impurities in a sample gas is provided which includes a housing (11) having an inlet (12) to allow the sample gas to enter the housing, an emitter (14) to generate ions from the sample gas, a field gradient to accelerate the ions toward a collector (16), the collector adapted to measure total ions, and an outlet (18) to allow the sample gas to exit the housing, whereby a change in total ions received by the collector indicates a change in the total concentration of impurities in the sample gas.

摘要： Method for improved packing and cooling of produce by improving the flow of ventilation air to the produce, and apparatus to practice the method. According to the present invention, baskets for the packing of fruit are provided with ventilation channels disposed upon a lower surface of the basket. Vent apertures communicate between the ventilation channels and the produce stored in the baskets. After packing the baskets with produce, they are loaded into trays. The trays are provided with tray vents which align with the ventilation channels. In this manner, entire pallets of produce-filled baskets can be efficiently chilled by introducing a flow of cooling air into the tray vents, through the ventilation channels and thence through the produce packed inside. The trays and baskets are sized so as to occupy all of the surface area of a standard shipping pallet, and to minimize the movement of the baskets within the trays, and of the trays with respect to one another.
