Various embodiments are directed to a collection media assembly for receiving one or more particles from a volume of fluid within a fluid composition sensor. In various embodiments, the collection media assembly comprises a housing, a transparent substrate, a collection media disposed upon the transparent substrate and configured to receive one or more particles from a volume of fluid received through a fluid inlet; and at least one alignment feature. The housing defines an open lower end configured for interaction with an imaging device, such that the one or more particles received by the collection media are visible through the transparent substrate from the open lower end. Each of the at least one alignment features is configured to engage a corresponding element disposed within the fluid composition sensor so as to constrain relative movement between the collection media assembly and the corresponding element in at least a first direction.

The inventive concept relates to a collector for collecting particles in air and a device for detecting particles in air comprising said collector. Said collector comprises a substrate, which is adapted to enable imaging of the particles, an adhesive layer arranged on a collector side of the substrate, said adhesive layer being formed by an adhesive material. The collector further comprises a protection element, which is configured to protect the adhesive layer before collection of particles. The collector is configured to allow release of protection of the adhesive layer by the protection element to expose an adhesive surface of the adhesive layer to ambient air for collecting particles on the adhesive surface. The collector is further configured for presenting a particle sample carrier having a smooth top surface and a smooth bottom surface for preventing light from being diffusely scattered by the particle sample carrier.

In certain aspects, the present disclosure provides unique devices and methods for detecting mold spores in a target environment. In accordance with some forms of the disclosure, such devices are configured to automatically calibrate and dynamically adjust the airflow rate through the device in response to one or more sensors.

Disclosed is a surface foreign substance detector for a transparent or translucent film. The surface foreign substance detector for a transparent or translucent film according to the present invention comprises: an optical unit; an optical housing accommodating the optical unit therein; a light emission unit emitting light to the film; and a film holder providing a loading surface such that the film can be loaded thereon and made of a light-absorbing material capable of absorbing light or reflecting the light at a predetermined ratio or less. According to the present invention, the holder supporter is manufactured by using a material capable of generating a predetermined electrostatic force or more between the holder supporter and the foreign substances floating in a surrounding space to prevent foreign substances floating or scattered in a surrounding work space from being moved to the film side, thereby improving detection reliability.

A method and apparatus for automatically transferring sections from a sample block to a tape and for transferring select sections to a slide. A tissue storage system for storing cut sections on the tape and digital storage system for storing photos and other information during the transfer of the sections can also be provided, thereby creating a tissue repository and data repository for future use.

The present disclosure related to apparatus and methods for removing waste of debris from a microtome blade, a microtome blade holder, or both. The invention also relates to automated systems and methods for cleaning a microtome.

A chemical sensor includes a sensor element. The sensor element includes a sensitive film and a treatment material. Physical properties of the sensitive film vary as bonding of a target substance to the sensitive film. The sensor element is configured to detect the variation in the physical properties. The treatment material is configured to carry out a treatment onto the target substance before the target substance bonds to the sensitive film. The treatment enhances the variation in the physical properties as compared to a case without the treatment.

An airborne particle collection system includes a monitoring device and a collection media. The monitoring device includes a housing having an air-intake slot, and a motor. The collection media includes an adhesive-coated tape contained within a removable cartridge inserted into the housing. The removable cartridge includes a particle intake zone, proximate to the air-intake slot, and through which the adhesive-coated tape is exposed to capture airborne particles passing through the air-intake slot, and an inspection zone at which the airborne particles captured at the intake zone are transported for optical imaging. The motor moves the airborne particles captured by the adhesive-coated tape from the particle intake zone to the inspection zone.
