Omniphilic and superomniphilic surfaces for simultaneous vapor condensation and airborne liquid droplet collection are provided. Also provided are methods for using the surfaces to condense liquid vapor and/or capture airborne liquid droplets, such as water droplets found in mist and fog. The surfaces provide enhanced capture and transport efficiency based on preferential capillary condensation on high surface energy surfaces, thin film dynamics, and force convection.

The present invention provides systems and methods for determining the cleanliness of a sample, the method including impinging high pressure fluid pulses on a sample disposed in a chamber to liberate particles therefrom and quantifying a number of the liberated particles to determine the cleanliness of the sample.

An emissions test apparatus is provided and may include a filter housing having at least one of a first RFID tag and a first bar code identifying the filter housing. A filter media may be selectively disposed within the filter housing and may include at least one of a second RFID tag and a second bar code identifying the filter media. A controller may link the filter housing and the filter media when the filter media is disposed within the filter housing based on information provided by the at least one of the first RFID tag and the first bar code and the at least one of the second RFID tag and the second bar code.

A method is disclosed comprising providing a biological sample on a swab, directing a spray of charged droplets onto a surface of the swab in order to generate a plurality of analyte ions, and analysing the analyte ions.

One variation of a pathogen detection system includes an air sampler and a cartridge. The air sampler includes: a housing defining an inlet and an outlet; a tunnel arranged within the housing and extending between the inlet and the outlet; a charge electrode arranged within the tunnel proximal the inlet; a cartridge receptacle arranged proximal the outlet and comprising a cartridge terminal; and a power supply configured to drive a voltage between the charge electrode and the cartridge terminal. The cartridge includes: a substrate; a collector plate arranged on the substrate and configured to collect charged bioaerosols moving through the tunnel; and a connector configured to transiently engage the cartridge receptacle to locate the substrate and the collector plate within the tunnel and electrically couple the collector plate to the cartridge terminal.

A method is disclosed comprising providing a biological sample on a swab, directing a spray of charged droplets onto a surface of the swab in order to generate a plurality of analyte ions, and analysing the analyte ions.

To analyze a generation source of a target component emitted in a form of a gas. To provide a generation source analyzing device comprising an acquiring section which acquires a concentration measurement value of a gas which includes a target component, and a concentration measurement value of a particle component which is generated in association with the gas, and an analyzing section which analyzes a distance from a measurement point to a generation source of the target component based on a concentration measurement value of the gas and a concentration measurement value of the particle component. The acquiring section may acquire a concentration measurement value of a precursor gas which becomes a raw material which generates the particle component, and a concentration measurement value of a secondary generated particle component which is generated from the precursor gas.

In an embodiment, the present invention is an apparatus, configured to collect emitted sample dose from a drug delivery device, wherein the sample dose is an aerosol, wherein the apparatus comprises a collection assembly and a removable plunger.

Provided herein are systems and methods allowing for automated sampling and/or analysis of controlled environments, for example, to determine the presence, quantity, size, concentration, viability, species or characteristics of particles within the environment. The described systems and methods may utilize robotics or automation or remove some or all of the collection or analysis steps that are traditionally performed by human operators. The methods and systems described herein are versatile and may be used with known particle sampling and analysis techniques and particle detection devices including, for example, optical particle counters, impingers and impactors.

The present disclosure is directed to methods and systems for detecting a substance in a sample gas. The methods and systems include separating the substance of interest in the sample gas, and introducing the separated sample gas into a detector. The systems and methods further include performing an analysis of the substance of interest.
