“…Adsorption isotherms were obtained for firebrick (87) and for Chromosorb-P (894) • Bens (28) compared different supports, including glass beads, treated in different ways by means of twocolumn GSC plots. In all cases, retentions were small and reproducible only with very small samples, indicating the low adsorption capacity of these materials.…”

“…Potentiometric attenuation of detector signals was accomplished automatically by means of microswitches which activate a stepping switch (87). In another instance, a manual attenuator, which applies precise bias voltages to the recorder input (193), was used; this principle was also applied to increase the accuracy of analyses for major concentrations of hydrogen (260).…”
