e 2 E 0 2 M X 1014 4n4 v 4 X 2 m3
e Z E o Z MX

< 0.1
Equation 11: (E)
=
e 2 E 0 2 MX 1014 ergs 8n2v2m2
Table 1: Electric field
( E O )
= 18.0 V/cm at 1 Torr Helium
These changes are necessary as a result of a typographical error which was carried through from Equation 10.
CORRECTION Removal of Water in the Distillation of Hydrocarbon Mixtures In this article by T. H. Gouw, Anal. Chem., 49, 1887 (1977), Figure 1 is incorrect. The correct figure is shown here.
