The intricate composition of Glycerides, C8-10 mono- and di-, necessitates advanced analytical techniques to ensure their quality, purity, and functional performance. NINGBO INNO PHARMCHEM CO.,LTD. utilizes a suite of sophisticated analytical methodologies to characterize these complex lipid mixtures, providing critical data for research and industrial applications. Understanding the precise ratio of mono- to diglycerides, the positional isomers, and the presence of any impurities is vital.

High-Performance Liquid Chromatography (HPLC) coupled with Evaporative Light Scattering Detection (ELSD) or Mass Spectrometry (MS) is a cornerstone of our analytical approach. This combination allows for the separation and quantification of the various glyceride species based on their polarity and molecular weight. Reversed-phase HPLC (RP-HPLC) is particularly effective in separating mono-, di-, and triglycerides, and can even differentiate between the specific C8 and C10 fatty acid chains esterified to the glycerol backbone. ELSD is crucial as glycerides lack chromophores for UV detection.

Gas Chromatography (GC), often coupled with Mass Spectrometry (GC-MS), is another powerful tool used by NINGBO INNO PHARMCHEM CO.,LTD. While requiring a derivatization step, typically trimethylsilylation, to increase volatility, GC-MS provides detailed compositional analysis. It enables the identification of individual mono- and diglyceride species and the confirmation of the specific fatty acid profiles. The high separation power of GC-MS is indispensable for detecting trace contaminants and ensuring product integrity.

Beyond chromatography, Nuclear Magnetic Resonance (NMR) spectroscopy plays a vital role in structural elucidation. Both ¹H and ¹³C NMR provide detailed information about the molecular structure, including the position of fatty acids on the glycerol backbone (stereospecific numbering) and the presence of different functional groups. This is particularly useful for distinguishing between positional isomers, such as 1-monoglycerides and 2-monoglycerides, which can exhibit different functional properties.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to rigorous quality control. By employing these advanced analytical techniques, we ensure that our Glycerides C8-10 mono- and di- meet the highest standards of purity and compositional accuracy. This meticulous approach guarantees that our clients receive reliable materials for their critical applications, whether in pharmaceutical development, food science, or chemical research.
