This paper shows that polar liquids form a coherent film on a glass surface which has first been covered by an approx. 0.001 渭 layer of carbon black. Several methods for producing these layers are described. Such pretreated glass capillaries show equal or better separation efficiencies than ...

The factors which influence the size of the heat-affected zone of a material on which a focused electron beam is incident are reviewed. These include the limitation of current density in the focused spot, which is given by the Langmuir relation, and also the limitation imposed by the ...
