AB  - The vapor condensation method can be used for forming an alternative flow of 
      liquid masses using a single solvent for alternative plugs flow liquid 
      chromatography (APFLC), described in our previous paper. APFLC is more effective 
      when adopting a T-shaped flow path and aqueous-organic solvents with a 
      liquid-to-gas volume ratio (bulk fraction; beta) ranging between 0.0006 and 0.004 in 
      an open tubular GC capillary column at below 70 degrees C. High-density plugs flow by a 
      T-shaped flow path leads to extremely high resolution. Alternative plugs flow is 
      formed when the liquid contact angle to the solid phase is above 75 degrees . An aqueous 
      mixture of the usual HPLC solvent can be readily used for APFLC. An EI-mass 
      spectrum is obtained that is comparable with that in the NIST library, except for 
      the DMF mixture medium. Due to low-pressure loss properties in the column, the 
      system does not require a high-pressure liquid pump. Solid hydrocarbon resin with 
      a contact angle to water of between 75 degrees  and 79 degrees , such as polystyrene and olefinic 
      polymers, is anticipated to be applicable to APFLC and hydro-membrane gas 
      chromatography (HMGC) by a consideration of their surface tensions.
