  2. Methylidynephosphane - Wikipedia

    en.wikipedia.org/wiki/Methylidynephosphane

    Methylidynephosphane (phosphaethyne) is a chemical compound which was the first phosphaalkyne compound discovered, containing the unusual C≡P carbon-phosphorus triple bond. Although isolated samples of methylidynephosphane are impractical, other derivatives have been well studied such as tert-butylphosphaacetylene.

    Atmospheric pressure chemical ionization (APCI) is an ionization method used in mass spectrometry which utilizes gas-phase ion-molecule reactions at atmospheric pressure (10 5 Pa), [1] [2] commonly coupled with high-performance liquid chromatography (HPLC). [3]

  9. Organic molecular tracers - Wikipedia

    en.wikipedia.org/wiki/Organic_molecular_tracers

    Organic molecular tracers in pollution control and environmental science are referred to as organic molecular markers or emission markers, and are compounds or compound classes. These tracers are of interest in the field of air quality because they can help identify particulate emission sources, as they are relatively unique to those sources.
