 Abstract
There have been settled the experimental conditions for the separation of some aromatic hydrocarbons from samples introduced in the chromatograph by injection and by thermal desorption. The identification of components has been achieved by means of retention times and also, by means of NIST spectra library. There have been collected air samples by adsorption on adsorbent tubes and there have been identified the separated components.

 Rezumat
Au fost stabilite condiţiile experimentale necesare separării hidrocarburilor aromatice din probele introduse în cromatograf prin injecţie şi prin desorbţie termică. Identificarea componenţilor s-a realizat prin indicii de retenţie şi cu ajutorul bibliotecii de spectre NIST. Au fost colectate probe de aer prin adsorbţie pe tuburi adsorbante şi au fost identificaţi componenţii separaţi.
