AbstractA simple method for the rapid and reliable analysis of solid matrices by direct introduction in the glass liner of a programmed-temperature vaporizer is proposed. The procedure requires only very small sizes (about 0.1 mg), does not require pretreatment or concentration steps and can be carried out in less than 40 min. A comparison between composition data obtaned from Rosmarinus officinalis leaves analysis by both simultaneous distillation extraction and direct introduction of the plant in the programmed-temperature vaporizer is also included. The proposed procedure allows the reproducible determination of the volatile composition of a plant with coefficients of variation of less than 5%.
