Determinación de ácidos grasos, glicerina libre y glicerina total en biodiésel
The validation of two analytical methods by gas chromatography was performed, in order to evaluate the quality of biodiesel (B100) and its usefulness as fuel. The performed methods were: determination of total content of fatty acid methyl esters (FAME) and determination of free and total glycerol co...

| Summary: | The validation of two analytical methods by gas chromatography was performed, in order to evaluate the quality of biodiesel (B100) and its usefulness as fuel. The performed methods were: determination of total content of fatty acid methyl esters (FAME) and determination of free and total glycerol content. Standards IN 14103: 2011 and ASTM D6584-13 were used as reference respectively. The performance parameters evaluated and documented for the two methods in the study were: linearity, detection limit and quantification limit, precision by repeatability and intermediate repeatability, truenes through a recovery test. Based on the evaluation of performance parameters and acceptance criteria it was concluded that the two methods are statistically and analytically under control; also both methods allow to establish a continuous assessment; demonstrating that the analytical procedures used are suitable for use as a routine screening test at CELEQ. |
