A pathogen detection apparatus includes an obtainer that measures a body temperature of a subject and outputs information indicating the body temperature, a collector that performs a pathogen collection operation for collecting a pathogen carried by the subject or a pathogen in air around the subject, a detector that performs a pathogen detection operation for detecting the pathogen collected by the collector, a notifier that provides a notification indicating a detection result obtained by the detector, and a controller. In a case where the body temperature output by the obtainer is higher than a predetermined threshold value and the detection result obtained by the detector is negative, the controller controls the detector to perform another pathogen detection operation for detecting a pathogen.

A device for detecting particles in air; said device comprising: a receiver for receiving a flow of air comprising particles; a particle capturing arrangement configured to transfer the particles from the flow of air to a liquid for collection of a set of particles in the liquid; a flow channel configured to pass a flow of the liquid comprising the set of particles through the flow channel; a light source configured to illuminate the set of particles in the flow channel, such that an interference pattern is formed by interference between light being scattered by the set of particles and non-scattered light from the light source; and an image sensor comprising a plurality of photo-sensitive elements configured to detect incident light, the image sensor being configured to detect the interference pattern.

A portable sampler, the sampler including a sampler assembly having a housing that includes a receiver defined therein for interchangeably receiving a number of removable inlet assemblies, the removable inlet assemblies including a respirable inlet assembly and a thoracic inlet assembly. The respirable inlet assembly includes a hybrid cyclone assembly, the hybrid cyclone assembly including an impaction stage and a cyclone in series. The thoracic inlet assembly includes an inlet slot configured to function as a size-selective inlet. Another thoracic inlet assembly includes a housing having a number of openings configured to receive a sample airflow; an inlet insert through which an inlet aperture is defined; a prequalification chamber defined between a lower surface of the housing and an upper surface of the inlet insert; and a protrusion extending downward from the lower surface of the housing into the inlet aperture of the inlet insert to from an inlet slot.

A dual spray chamber apparatus is described. In one or more implementations, the dual spray chamber apparatus includes a first cyclonic spray chamber for receiving an aerosol and conditioning the aerosol to separate a first conditioned portion of the aerosol from a second portion of the aerosol. The first cyclonic spray chamber defines a first chamber interior and comprises an input port in fluid communication with the first chamber interior. The dual spray chamber apparatus also includes a second spray chamber coupled with the first cyclonic spray chamber for receiving the first conditioned portion of the aerosol and further conditioning the first conditioned portion of the aerosol. The second spray chamber defines a second chamber interior and comprises an output port for expelling a first further conditioned portion of the first conditioned portion of the aerosol from the second chamber interior.

To provide a method with which it is possible to ascertain a gas concentration in a furnace rapidly, and to charge an amount of fuel and/or oxygen corresponding to the state within the furnace, and with which it is possible to reduce the device maintenance load. In order to solve the abovementioned problem, this method for analyzing components contained in flue exhaust gas of a furnace includes: a sampling step of collecting a portion of the flue exhaust gas from a flue; a dust removal step of using a centrifugal dust collecting device to separate out dust in the flue exhaust gas collected in the sampling step, to yield an analysis gas; a measuring step of measuring components in the analysis gas to obtain the concentration of carbon monoxide in the analysis gas; and an analysis gas discharging step of causing the analysis gas to be sucked by an ejector.
