Sažetak
A simple and sensitive gas chromatographic method using the single columm technique withouth an extreme working temperature range for the separation od O2, N2, CO and CO2 was developed. The analysis was performed on micropacked columns filled with active charcoal with particle size distribution smaller than 20 micrometer, using a microthermal conductivity detector. The results obtained show that such a columm is capable of good separation of O2, N2 and CO at room temperature. To shorten the elution time of CO2 the temperature has to be elevated above ambient tempoerature by about 100 C. Employing for ethylene removal the subtraction method introduced in gas chromatography very early by Ray, the achieved separation of inorganic gases was usefully applied for the detemination of inorganic gases in high purity ethylene.
