摘要： Embodiments of the invention can sample particulates, aerosols, vapors, and/or biological components of ambient air utilizing spherical air-sampling filters. Components of the embodiments may include a storage magazine for holding a plurality of spherical air-sampling filters, an air-sampling manifold configured to deliver an air-sampling filter from the storage magazine to a sampling location, and an air compressor to perform an air sampling operation and to transport a used air-sampling filter away from the sampling location. Operation of some embodiments may begin by rotating a slotted drum within the air-sampling manifold to deliver an air-sampling filter from the storage magazine to the sampling position. Operation may continue by using the air compressor to draw air from an ambient environment through the air-sampling filter. After sampling is complete, the air compressor may be utilized to pneumatically transport the used air-sampling filter away from the sampling position to a filter retrieval location via a transport tube. These operations can be pre-programmed locally or triggered by remote communication. Operation may continue uninterrupted due to a plurality of unused air-sampling filters retained in the storage manifold. Because operations can be triggered remotely and air samples are autonomously transported off site, embodiments of this invention eliminate unnecessary risks to human health created by other air-sampling devices, which require an operator to be present at a potentially hazardous sampling site to activate the device or retrieve air samples. Embodiments of the invention can be installed pre-emptively to eliminate risks to human health created when an operator must deliver a portable air-sampling device to a potentially contaminated sampling site. Furthermore, embodiments of the invention allow rapid retrieval of air samples following sample collection, which can expedite analysis and identification of aerosols and consequently help minimize human exposure to potentially dangerous and life-threatening chemical and biological contaminants.

摘要： A portable apparatus to sample and analyze volatile organic compounds in breath air, includes:a box internally divided in two internal sections, each housing a sample collecting tube or filter in turn containing a stationary phase suitable for retaining determined analytes, as drugs and/or respective metabolites, having specific chemical physical properties, contained in breath air;a pre-accumulation chamber for receiving breath air from the outside through a breath entrance connection and for feeding the received breath air to the sample collecting filters housed in the two sections, with these two sample collecting filters being connected in parallel to the chamber; anda tool application kit for removing the two sample collecting filters from the respective sections in the box of the apparatus, in a way that avoids any contamination thereof, and for extracting the analytes that are retained by the stationary phase on the same two sample collecting filters.

摘要： A concentrator that is operable to concentrate particles of target material from a high flow rate sampled airflow into a low flow rate secondary airflow. The concentrator may have an array of radially arranged blades. Each blade may have a sampled airflow inlet that uses centrifugal force to concentrate the particles into a central portion of the sampled airflow passing through it. Downstream, the blade may also have primary airflow outlets and knife-edged secondary airflow inlets that divide the sampled airflow into a pair of lateral, high flow rate primary airflows from which the particles have been depleted, and a central, low flow rate secondary airflow which carries the concentrated particles.

摘要： A test unit having a light source (e.g., a laser) for illuminating an aerosol sample directed into a test chamber and a removable insert for the test unit. The test unit includes at least one detector for detecting the effect of the aerosol sample on light, i.e., the detector detects at least one property of light after the light has illuminated the aerosol sample. The removable insert may take a number of different forms. For example, the removable insert can form at least a portion of an unsealed or sealed test chamber when installed in an operating position. Further, the removable insert may include a removable support and at least one film or collection substance connected or applied to the removable support. The at least one film could be a filter or a non-filter. The filter could be a polarization filter (i.e., horizontal or vertical) or a fluorescence filter.
