This standard solution is primarily used for the calibration and performance testing of Gas Chromatography-Flame Ionization Detector (GC-FID) systems. It ensures the accuracy and reliability of the GC-FID instrument by providing a known reference for detecting and quantifying analytes. The solution is essential for verifying the detector's sensitivity, linearity, and response consistency over time. It is commonly employed in quality control laboratories, environmental testing, and pharmaceutical analysis to maintain compliance with regulatory standards. By using this solution, analysts can confirm that the GC-FID system is functioning optimally, ensuring precise and reproducible results in the analysis of complex mixtures.
