Abstract
The properties and limitations of a highly efficient gas chromatographic separation column are described. The column is of importance in the analysis of hydrocarbon emissions as it has the following advantages: high separation efficiency; good detection performance owing to a high signal-to-noise ratio; simultaneous determination of aromatics in the presence of other hydrocarbons in the C 1–C 9 range in a short time and without the need for a multi-column techniqe; simple on-line computer connection even in the parts per 10 9 range. The preparation of the column and its applications and use with suitable measuring equipment are described in detail.
