Abstract
BANGHAM and co-workers1, using charcoal blocks as adsorbents, found that the expansion accompanying adsorption of mobile films is proportional to the film pressure. Having established this, they were able to use the expansion of the block as a measure of the film pressure, and the method proved particularly suitable for detecting phase changes in the adsorbed films2,3,4.
