What is the process of conducting furan analysis in transformer oil by HPLC?

The process of conducting furan analysis in transformer oil by HPLC involves extracting furan compounds from the oil sample using a suitable solvent. The extracted solution is then filtered and injected into the High-Performance Liquid Chromatography (HPLC) system. The HPLC separates the furan derivatives based on their chemical properties, allowing for quantification and identification. This analysis helps assess the condition of the transformer insulation system and predict potential failures.
