  • Atmospheric Plasma Analysis by Molecular Beam Mass Spectrometry (.pdf)
    ]. This original design was adapted to include a second, concentric gas inlet in order to study mixtures of gases. The inner. gas inlet delivers helium to the plasma volume and the outer gas inlet carries different percentages of the gas to be studied. (oxygen, nitrogen, nitrous oxide and carbon
  • Atmospheric Pressure Plasma Analysis by Modulated Molecular Beam Mass Spectrometry (.pdf)
    , Warrington, WA5 7UN, England. ABSTRACT: We describe a molecular beam mass spectrometer with automated beam modulation and present mass and energy resolved. measurements from an RF plasma `needle' operating at atmospheric pressure. The automation of the beam modulation. allows the neutral components
  • Bearing Failures - Causes and Cures: Proper Storage and Handling
    coatings can be replaced easily and economically. Also, never remove a bearing from its carton before it is to be used because moisture and dirt can contaminate the bearing. Bearings are wrapped in a special neutral, acid-free paper, and they should be rewrapped in such paper for storage
