Modern Vapor Pressure Measurements Based on the Knudsen-Effusion

  • Josef Tomiska
Part of the NATO ASI Series book series (ASIC, volume 286)

Abstract

The Knudsen method of molecular effusion is employed successfully to determine small vapor pressures (< 20 mbar) — even at temperatures higher than 1500 K. The various techniques are rewiewed briefly. Special emphasis is placed (i) on two newer automatic apparatus for pressure measurement by the TORKER-method (Torkometer and Computer-operated dynamic torsion pendulum) as well as (ii) on the newer PENKER-method (Pendulum electronically balanced Knudsen-effusion recoil).
