Laughing Gas (instrumental) Laughing Gas (instrumental) "Laughing Gas" was a song performed by Quiet Riot at all the live performances while Randy Rhoads played with the band. It was never recorded onto an album until a live bootleg performance was enhanced (with rerecorded vocals) and placed on "The Randy Rhoads Years". The improvised solo was just over 6 minutes long and contained clips from future songs of Ozzy Osbourne including, "Goodbye to Romance", "Mr. Crowley", "Dee", and "Crazy Train". The solo outlined Randy's talent and productivity level at such a young age. This solo also contained a reference to William Tell Overture and
Chemical ionization Chemical ionization Chemical ionization (CI) is a soft ionization technique used in mass spectrometry. This was first introduced by Burnaby Munson and Frank H. Field in 1966. This technique is a branch of gaseous ion-molecule chemistry. Reagent gas molecules are ionized by electron ionization, which subsequently react with analyte molecules in the gas phase in order to achieve ionization. Negative chemical ionization (NCI), charge-exchange chemical ionization and atmospheric-pressure chemical ionization (APCI) are some of the common variations of this technique. CI has several important applications in identification, structure elucidation and quantitation of organic compounds. Beside the applications in analytical chemistry,
