Buffer gas Buffer gas A buffer gas is an inert or nonflammable gas. In the Earth's atmosphere, nitrogen acts as a buffer gas. A buffer gas adds pressure to a system and controls the speed of combustion with any oxygen present. Any inert gas such as helium, neon, or argon will serve as a buffer gas. Buffer gases are commonly used in many applications from high pressure discharge lamps to reduce line width of microwave transitions in alkali atoms. A buffer gas usually consists of atomically inert gases such as helium, argon, and nitrogen which are the primary gases used. Krypton, neon,
Most common words in Spanish (CREA), a text corpus compiled by the Real Academia Española (RAE). The RAE is Spain's official institution for documenting, planning, and standardising the Spanish language. A "word form" is any of the grammatical variations of a word.
