DETECTEUR PIEZOELECTRIQUE [3 records]

English

Subject field(s)
  • Analytical Chemistry
DEF

A small crystal, such as quartz, is coated with a stationary phase material and placed at the end of the g.c. column; as solutes are eluted from the column they pass over the coated crystal and give rise to sorption and desorption on the crystal with corresponding frequency changes in the piezo-electric effect related to the quantity of material sorbed.

Piezoelectric Sorption Detector. Piezoelectric quartz crystal, long used as frequency and time standards to one part in 108 or better, have been shown by King to be selective gas detectors when coated with various chromatographic liquid phases. Used as detectors, such coated crystals have several advantages: (1) sensitivity increases with solute or sample boiling point, (2) detectors selective to compound type can be made with response times of the order of 0.05 sec, and (3) the output signal is a frequency which simplifies integration of peak areas and digital presentation of data.
