... Winefordner et al. described a special, more sensitive cell based on changes in dielectric constant and constructed to allow gas flow between the plates of a capacitor which is a part of the tank circuit of a 70-Mc/sec Clapp oscillator, the output of which is beat against that of a reference oscillator. With the difference frequency between oscillators adjusted to zero with pure carrier gas flowing through the detector, the presence of a foreign vapor in the cell will produce a different frequency which is linearly related to the amount of material introduced through an injection port in the carrier gas stream and inversely proportional to the absolute temperature for a given component at a constant density or concentration in the cell and for a particular operating frequency.  2, record 1, English, - Clapp%20oscillator
