Auteur : Serré, Robert,Définition
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.
