• silanol
  • Columns are basically just glass tubes containing innumerable free silanol groups onto which the desired chemistry (a liquid polymer) is attached. (labmanager.com)
  • preparative
  • The classical preparative chromatography column is a glass tube with a diameter from 5 mm to 50 mm and a height of 5 cm to 1 m with a tap and some kind of a filter (a glass frit or glass wool plug - to prevent the loss of the stationary phase) at the bottom. (wikipedia.org)

  • strongly
  • However, the disadvantage with SFC is the compressibility of the mobile phase generates serious internal pressure/density gradients which may lead to set instrumental conditions deviating more or less strongly from the real conditions in the column. (labmate-online.com)
