Plasma afterglow

[1] The external electromagnetic fields that sustained the plasma glow are absent or insufficient to maintain the discharge in the afterglow.

[3] The first flowing afterglow ionization studies began in the early 1960s in an effort to understand atmospheric ion chemistry.

Temporal plasma is often used to replicate ionic reactions in atmospheric conditions in a controlled environment.

[4][5][6] Flowing afterglow ion sources usually consist of a dielectric discharge that gases are channeled through to be excited and thus made into plasma.

Flowing-afterglow mass spectrometry uses a flowing afterglow to create protonated water cluster ions in a helium or argon carrier gas in a flow tube that react with sample molecules that are measured by a mass spectrometer downstream.

[9] Stationary afterglow (SA) is a technique for studying remote plasma that consist of a gaseous mixture inside a bulb that is subjected to an ionizing pulse.

After said ionizing pulse the ion composition of the mixture is measured as a function of time at the wall of the containing bulb.

Plasma afterglow has shown to be an effective means of cleaning and sterilizing difficult to take apart machinery and glassware.
