Calibration (regression) of spectrometers for determination of triglycerides of fatty acids in foods and serum

Triglycerides of fatty acids (TGFA) form an important part of human nutrition. The spectrometry of TGFA has obvious advantages over conventional chromatography and is possible with at least three types of near-infrared spectrometers. The report presents the results of calibration of these spectrometers by the regression method on latent structures to determine the content of clinically significant TGFA in food, preparations and blood serum of cardiac patients.
