Opis

Opis ogólny

Stearic acid belongs to the group of saturated long-chain fatty acids, commonly found in animal and plant fats.

Zastosowanie

This analytical standard can also be used as follows:

• Development of a non-destructive Vis-NIR reflectance spectroscopy-based method for the detection of four fatty acids in 93 samples of seven different edibles oils
• Simultaneous identification and quantification of fatty acids from blood plasma samples after their methyl derivatization by large-volume injection (LVI) gas chromatography combined with vacuum ultraviolet spectroscopy (GC-VUV)
• Determination of the fatty acid composition of sunflower seed oils extracted from 93 different sunflower varieties by near-infrared reflectance spectroscopy (NIRS) combined with modified partial least squares (MPLS) and partial least squares (PLS) regression methods
• Identification and quantification of fatty acids in various herbal anti-diabetic formulations by gas chromatography-mass spectrometry (GC-MS)
• Multi-residue analysis of oleic acid and other related fatty acids using a derivatization-free method based on gas chromatography-flame ionization detection (GC-FID)
• Ultra-performance liquid chromatography-mass spectrometry (UHPLC) method-based separation, identification, and determination of eight saturated and unsaturated fatty acids in eight different commercial samples of olive oil without any prior sample treatment
• Development of a liquid chromatography-mass spectrometry (LC-MS) method to measure seven fatty acid esters of hydroxy fatty acids (FAHFAs), four fatty acids, and four cardiovascular-related biomarkers in plasma samples of 57 healthy individuals
