Reproducibility and Repeatability in Calibration for Gas Chromatography in Fusel and Esters Analysis

Abstract

Gas chromatography is a very sensitive method of analysis that requires understanding what will be analyzed in order to choose the correct parts and analysis parameters. This project seeks to find the ideal conditions to achieve reproducibility and reliable values of samples with high and low levels of fusel and esters. Chromatography of two different liners was evaluated and the calibration levels were created separately to maintain the individual conditions of analysis. The result of this study helped to obtain better reproducibility in the reference samples. On the other hand, maintaining two calibration conditions created flexibility in the use of GC instruments, which could speed up the customer's response to important decisions.
