• Description:
  A low energy dry sampling system is developed for the efficient collection of low concentrations of alkyl phosphonates in the atmosphere so that sufficient material can be collected in a short time for an infrared or mass spectrometric analysis. A procedure is developed to collect ultra-micro concentrations of hydrogen fluoride in the air using a cellulose acetate filter impregnated with sodium formate. Data are given for the collection efficiencies of untreated filter media and recoverability, with details of stationary phase tests, filter preparation, collection efficiency tests, dependence on loading, breakthrough determination, collection efficiency of untreated glass fiber filters, effect of blocking of silanol groups, regeneration of silanol groups, adsorption on inorganic salts, negative correlation of vapor pressure and collection efficiency, effect of loading and time on collection efficiency, and tests with DIMP.
