Abstract: Total Volatile Organic Compounds(TVOC) blended standard solution was usedto explore the detection method of TVOC by GC and to determine the best chromatographic conditions. The improved process used only 26.1min, which is 25.9 min shorter than that of the original one(52 min) described in GB/T1 8883-2002. The separating degree of each component in the TVOC blended standard solution was greater than 99%. The RSD of precision was between 1.05% and 2.89%. the recovery was between 95% and 102%, andthe detection limit was 0.020 μg.
Key words: gas chromatography; total volatile organic compounds; improvement of chromatographic conditions
