Analysis of Dissolved Gas Analysis (methane, ethane, propane,…) has traditionally been performed following EPA 3810 and RSK175 These methods involve several manual steps, hence, they are not ideal for meeting the demands of modern laboratories. The electric utilities and other industrial partners have developed more efficient alternatives for the analysis of DGA, due to their increasing need for this analysis. An example of this alternatives is ASTM D3612 Method C. This method specifies the use of automated headspace sampling of the transformer oil, which allows for higher throughput over other sampling methods for DGA analyses, such as vacuum extraction or the use of a stripper column (e.g., ASTM D3612 Methods A and B, respectively). Using current techniques and technologies, this applicated gas chromatography system increases throughput and serviceability over previous designs allowing for improved monitoring of DGA. In this presentation we will share the results from the evaluation of the method performance and discuss its applicability for environmental analysis.
