摘要： An airborne particulate sampling monitor for collecting particulate in either a solid, liquid or gaseous state. The monitor includes at least two intakes (18, 1) each of which accepts airborne particulate. Paired with and coupled to each intake is an appropriate particulate filter (20) for sampling accepted airborne particulate. A vacuum pump (28) establishes air flow into one of the intakes and a sampling process controller (24), coupled between each intake and filter pairing and to the vacuum pump, controls the vacuum pump's establishing of air flow into a selected particulate intake. Preferably, the vacuum pump and sampling process controller reside within a hub unit to which multiple satellite units (14) can be coupled such that each satellite unit employs the vacuum pump and sampling process controller of the hub unit. Due to central processing, conditional sampling at one or more of the units is possible. Further details and manual particulate sampling methods are presented.

摘要： A gas particle partitioner (10) removes particles from an aerosol (28) with high efficiency and with no or minimum changes to the thermodynamic conditions and chemical composition of the gas phase of the aerosol. A permeable grid electrode (24) surrounds a corona wire (32) and separates an interior corona discharge area (34) from an exterior aerosol charging zone (30). A particle free fluid (42) washes the corona discharge area to minimize any transport of gas components produced by corona discharge to the aerosol. The charged particles (44) in the aerosol are deflected by an electric field F in a fractionator (16) to selectively produce a particle free sample stream (46), which is then separated by a flow splitter (18) from the aerosol.

摘要： High-flow rate, low-noise, gas sampling apparatus (10) for collecting particulate such as biological, chemical, and radioactive material from a gas on a collector (40) includes a housing (12) having an inlet (14) and an outlet (16) and a fan (30) disposed within the housing for drawing the gas into the inlet, past the collector for sampling, and exhausting the gas through the outlet. The fan is operable to produce a flow of gas through the housing of greater than about 50 liters per minute with a noise level emitted from the apparatus being less than about 60 decibels. The apparatus may also include a sensor (78) for the detection of radioactive material collected on the collector, a processor (62) for monitoring the sampling, and the apparatus may be linked to a communications network (84) such as the Internet.

摘要： In an inertial mass measurement instrument (10), an active force compensator (46) compensates for inertial forces (IF) transmitted by an oscillating elastic element (12) to a primary support (18) of the instrument (10). The compensator (46) applies equal and opposite compensating forces (CF) to the primary support (18) along an effective line of action (48) of the oscillating element. Application of the compensating forces results in a substantially zero net acceleration of the primary support (18) and avoids measurement inaccuracies attributable to changes in properties of secondary support elements (36).

摘要： A carrier (30) supporting multiple filters (90) is inserted jointly with the filters into an air sampler (10). The carrier (30) includes an indexing structure (80) to ensure correct positioning within the air sampler (10). A memory device (84) physically associated with the carrier stores sample collection data provided by the air sampler (10). The stored data can be read by a read/write station (102) at a lab (100), and transmitted to a processor (108). The processor (108) also receives a weight reading from a communicating balance (110) for each collected sample, and calculates therefrom mass concentration for each sample.

摘要： Particulate concentration of diesel exhaust is measured by collecting the diesel particulate on a filter (18) while measuring the amount of exhaust passing through the filter (18). The filtered particulate is then heated in an oxygen rich environment (32) to oxidize carbon within the particulate to carbon dioxide. The amount of resulting carbon dioxide is measured in meter (38) to derive a corresponding measurement of the amount of filtered particulate. Particulate concentration is calculated by comparing the amount of exhaust passed through the filter. Filtered particulate can be heated incrementally to obtain a measurement of volatile components within the particulate prior to the oxidation of the non-volatile carbon component. The filter (18) employed to collect the particulate is of a high temperature resistant type making it reusable and can be either integral with or inserted into the oxidation chamber of the instrument. Oxidation of the particulate inherently concurrently cleans the filter for reuse.

摘要： A sampling cartridge (30) for a gas sampling apparatus (10) includes a shell (60) having a cylindrical wall and a sampling window (56) extending through the wall. A pair of spools (78, 80) are coaxially and internally positioned within the shell. The spools are independently rotatable relative to the shell. A first spool (78) may include multiple interval sample collectors (48) while the second spool (80) includes a duration sample collector (50). Each spool also has a window closing surface (58, 58') which is positioned adjacent the window (56) whenever an access door (18) of the gas sampling apparatus is opened. The sampling cartridge may also include a fully encapsulated section (80) of sample collector material as a negative control, and an integral RF tag (90) for storing chain of custody information including personal identification information of a cartridge replenisher.

摘要： Carbon particulate concentration of diesel exhaust or other sampled gas is measured by collecting the particulate on a high efficiency filter (18) while measuring the amount of sampled gas passing through the filter (18). The filtered particulate is then heated in an oxygen rich environment (16) to oxidize carbon within the particulate to carbon dioxide. The amount of resulting carbon dioxide is measured with a closed measurement loop (30) to derive a corresponding measurement of the amount of filtered particulate. Particulate concentration is calculated by comparing the amount of carbon particulate with the measured amount of sampled gas passed through the filter. Filtered particulate can be heated incrementally to obtain a measurement of volatile carbon components within the particulate prior to the oxidation of the non-volatile carbon component. The filter (18) employed to collect the carbon particulate is of a high temperature resistant type making it reusable and can be either integral with or inserted into the oxidation chamber (16) of the instrument. Oxidation of the particulate inherently concurrently cleans the filter (18) for reuse. An upstream preseparator (15) can extend the life of the high efficiency filter (18). Particulate can also be collected for analysis by using an accelerating impaction nozzle (68) in conjunction with a heatable impaction plate (70).
