| Abstrakt: | A photoionization detector (P.I.D.) with separated discharge and detection compartments, enabling detection of eluted substances under normal pressure, has been developed. A detection mechanism was formulated for these conditions and relations for the P.I.D. signal were derived. The detector can measure all substances with ionization potentials less than 11.4 eV. A detection limit of 10−14 mol/s for benzene, with a linear dynamic range of 104, was attained. |
