The aerosol spray canister invented by USDA researchers, Lyle Goodhue and William Sullivan.. The concepts of aerosol probably go as far back as 1790. [1] The first aerosol spray can patent was granted in Oslo in 1927 to Erik Rotheim, a Norwegian chemical engineer, [1] [2] and a United States patent was granted for the invention in 1931. [3]
This approach to laser spray ionization is a hybrid of three basic techniques for the generation of gaseous ions from the condensed phase, i.e., energy-sudden activation, nebulization and the action of an electric field. [1] Laser spray mass spectrometry can faithfully reflect the solution-phase characteristics of biomolecules.
He submitted an application for an aerosol spray can in October 1926. The can could dispense different fluids using a chemical propellant. The Norwegian patent was granted in June 1929. He filed the United States patent application on 30 September 1927 and it was approved on 7 April 1931. [1]
The charged aerosol detector (CAD) is a detector used in conjunction with high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) to measure the amount of chemicals in a sample by creating charged aerosol particles which are detected using an electrometer.
Robert Henry Abplanalp, (April 4, 1922 – August 30, 2003) was an American inventor and engineer who invented the modern form of the aerosol spray valve, the founder of Precision Valve Corporation, a Republican political activist, and a close confidant of Richard Nixon.
Laser-ultrasonics uses lasers to generate and detect ultrasonic waves. [1] It is a non-contact technique used to measure materials thickness, detect flaws and carry out materials characterization. The basic components of a laser-ultrasonic system are a generation laser, a detection laser and a detector.
Spray paint (formally aerosol paint) is paint that comes in a sealed, pressurized container and is released in an aerosol spray when a valve button is depressed. The propellant is what the container of pressurized gas is called. When the pressure holding the gas is released through the valve, the aerosol paint releases as a fine spray. [1]
Mace is the brand name of an early type of aerosol self-defense spray invented by Alan Lee Litman in the 1960s. The first commercial product of its type, Litman's design packaged phenacyl chloride (CN) tear gas dissolved in hydrocarbon solvents into a small aerosol spray can, [1] usable in many environments and strong enough to act as a deterrent and incapacitant when sprayed in the face.
