摘要： A compressed gas sampling device is shown which includes a pressure reducing orifice to permit collection of a gas sample at a low pressure. A filter cartridge is connected between a flow meter and a pressurized source for analysis and gas is passed through the cartridge for a predetermined period of time. The cartridge may then be analyzed by a laboratory to determine contaminants which may be present in the source gas under analysis.

摘要： Environmental gases, e.g. air are collected in an apparatus wherein a sample bottle containing a metering orifice for admitting the gas is contained within and cooled by a bath of liquid cryogen thus creating a partial vacuum inside the bottle to draw gas into the bottle where it is condensed and stored. The apparatus includes a source of cryogenic refrigeration disposed in an evacuated space above the liquid cryogen to condense liquid cryogen boil-off. By combining evacuation and cryogenic refrigeration the sample bottle holder can be rapidly cooled to operating temperature.

摘要： Provided are devices and methods for monitoring flow rate in aerosol particle counters. The particle sensor has a particle counter, a flow measurement orifice comprising a differential pressure sensor for measuring differential pressure (DP) across the flow measurement orifice during particle sensor operation and a critical flow orifice. A vacuum source pulls ambient gas through each of the particle counter, flow measurement orifice and critical flow orifice. An atmospheric pressure sensor measures atmospheric pressure (AP) and a bench pressure sensor measures pressure in the particle sensor (BP). The output from the sensors is used to identify a flow condition, such as by a monitor operably connected to each of the differential pressure sensor, atmospheric pressure sensor and bench pressure sensor. In this manner, deviation in flow rate from a target flow rate is readily monitored without the need for expensive sensors or other flow-controlling components.

摘要： A regenerative blower (128) pulls ambient air (101) into a flow (138) within a particle sensor (106) and a laser (134) illuminates the flow to generate radiation (140) indicative of particles within the flow. A detector (142) detects the radiation; and particle sensing electronics (144) senses particles within the flow at a preselected volumetric flow rate, e.g., 1CFM. A plurality of pressure sensors (120, 122, 124) and a blower voltage controller (126) responsive to the sensors adjusts the speed of the blower to achieve the preselected volumetric flow rate. A high efficiency exhaust filter (152) filters air from the blower. An airflow path (148) between the particle sensor and the blower has at least one bend between the particle sensor and the blower to increase compactness of the system. An aerosol manifold (104) is connected for fluid communication with an inlet (102) of the particle sensor such that the blower draws air from the manifold at the preselected volumetric flow rate. The manifold samples ambient atmospheric air at a second CFM rate, e.g., 3CFM, that is greater than the preselected volumetric flow rate. A turbomolecular pump (300) can replace the regenerative blower for high pressure differential particle sensing environments.
