Summary
The paper describes the possibilities of on-line selective sampling as an on-line fraction technique for the analysis of essential oils.
Selective sampling is a micro-separation method, on-line with on-column injection, carried out directly in the syringe body by means of a selective elution of the sample through a fraction cartridge.
The paper reports a method of both preparing and standardizing silica gel cartridges, and illustrates through some examples the results of some elution series of solvents on different essential oils.
