Aerosol spray is a type of dispensing system which creates an aerosol mist of liquid particles. It comprises a can or bottle that contains a payload, and a propellant under pressure. When the container's valve is opened, the payload is forced out of a small opening and emerges as an aerosol or mist. Aerosol spray can
Cascade impactors are strictly measurement-related devices. In addition to measuring the range of substances moved through an opening by aerosol, the impactor can also be used to determine the particle size of the distributed substance. A cascade impactor collects its samples in a graduated manner.
Most aerosol paints also have a metal, marble, glass or plastic ball called a pea inside of the can, which is used to mix the paint when the can is shaken. Aerosol propellants consist of flammable gas combinations that can lead to fire and explosions if they are sprayed, punctured, or exposed to flames.
An example of a HMIS III label for Diesel fuel. The Hazardous Materials Identification System (HMIS) is a proprietary numerical hazard rating that incorporates the use of labels with color bars developed by the American Coatings Association as a compliance aid for the OSHA Hazard Communication (HazCom) Standard.
Bates numbering is commonly used as an organizational method to label and identify legal documents. Nearly all American law firms use Bates stamps, though the use of manual hand-stamping is becoming increasingly rare because of the rise in electronic numbering, mostly in Portable Document Format (PDF) files rather than printed material.

Spray nozzles can have one or more outlets; a multiple outlet nozzle is known as a compound nozzle. Multiple outlets on nozzles are present on spray balls, which have been used in the brewing industry for many years for cleaning casks and kegs. [2] Spray nozzles range from those for heavy duty industrial uses to light duty spray cans or spray ...
A diagram showing the operation of a tapered element oscillating microbalance instrument. The TEOM uses a hollow glass tube as a microbalance. Incoming particles are deposited on a filter at the tip of the tube, and the added mass causes a change in its oscillation frequency which is detected electronically.
