Method of determining the effluent curves of vapors of organic substances in a wide range of concentrations in an investigation of the dynamics of adsorption

Abstract

1. A method of determining concentrations based on the use of a flame-ionization detector was used to investigate the dynamics of adsorption in a broad range of concentrations behind the layer of adsorbent. 2. This method was carried out in an experimental instrument, a DIP-3 gas analyzer, and permits determination of the concentrations of vapors of organic substances in various carrier gases in the interval from the order of 10−5 mg/liter to the initial concentration. 3. A diffusion method for obtaining low concentrations of vapors of organic substances was used to calibrate the DIP-3 flame-ionization detector. 4. Examples are cited of the investigation of effluent curves of tertiary butyl benzene for the range of concentrations behind the layer of activated charcoal from the order of 10−5 to ~1 mg/liter.
