- Title
Circular Chromatography of Terpenes on Adsorbent Coated Glass.

- Abstract
THE 'chromatostrip' method of Kirchner, Miller and Keller1 for the separation and identification of terpenes and related compounds is a useful technique in a field where chromatography has been little applied. The method consists essentially of coating glass strips with an adsorbent (silicic acid), oven-drying and cooling in vacuo over potassium hydroxide. The oil is spotted near one end of the strip, which is developed by capillary ascent in a similar manner to paper strips. Spots or zones are located by spraying with reagents, one of the most useful being concentrated sulphuric acid, with which most components of essential oils give characteristic colours. Kirchner et al. have indicated the usefulness of the method for two-dimensional chromatography, and Reitsema2 has used glass plates on which a number of oils were directly compared.
