Abstract: The systems and methods provided herein relate generally to the prevention of migration of condensate in a condensation particle counter between components designed to handle condensate (e.g. saturator, condenser, condensate reservoir) and components which may be damaged by the condensate (e.g. detection and flow control devices).

Abstract: Provided are impactors for detecting biologics having an adjustable separation distance between an impact surface and the intake aperture, including the exit of the intake aperture. The impactor has a sampling head having at least one intake aperture and an exit, an impactor base comprising an impact surface, wherein the impact surface opposibly faces the sampling head exit and is separated from the exit by a separation distance. The separation distance is continuously adjustable between a minimum separation distance and a maximum separation distance and can accommodate impact surfaces having different heights by positioning the impact surface, irrespective of height of the impact surface, at an optimal separation distance from the sample intake aperture, such as by a rotation-type mechanism with a change in distance indication provided to a user by a separation distance step indicator.

Abstract: Provided are systems and methods for accurate sensing of particle concentrations in fluids by employing a particle impactor system that allows for collection, growth and analysis of biological particles. The disclosed systems and methods make use of a pressure based flow sensor which permits the particle impactor system systems to accurately and reliably provide measurements of biological particle concentrations in the ambient environment. By incorporation of pressure sensors and pressure measurements into the flow measurement techniques, embodiments provide for the ability to use a particle impactor system to accurately measure environmental biological particle concentrations at a variety of atmospheric pressure conditions, such as at high altitude or with minimal perturbation from atmospheric weather conditions, without requiring recalibration or other adjustment of the sensors and control systems.

Abstract: The invention provides devices and methods for sampling, detecting and/or characterizing particles. Devices and methods of the invention, including particle samplers, impactors and counters, include a filter component for removing particles in the exhaust flow of the device, for example, to eliminate or minimize the potential for the device itself to provide source of particles in an environment undergoing particle monitoring. This aspect of the present devices and methods is particularly useful for monitoring particles in manufacturing environments requiring low levels of particles, such as cleanroom environments for electronics manufacturing and aseptic environments for manufacturing pharmaceutical and biological products.

Abstract: The present invention relates to an automatic injector having a drive assembly with an actuator extending from the rearward end portion of the housing and a removal resistant cover for preventing unintended operation of the actuator. The present invention also relates to a sealing arrangement wherein the needle is sealed within a sterilized needle chamber by at least three sealing members which cooperate to form the chamber. Also, the present invention relates to an injector in which the cartridge is mounted to a tubular cartridge mounting portion of the needle carrier with an annular sealing member disposed therebetween. The cartridge mounting portion has at least one generally axially extending groove which allows air to escape from the cartridge mounting portion as the cartridge is being moved forwardly to a medicament supplying position.
