General description
Application
- Simultaneous determination of vitamin A and all four tocopherol isomers in human serum samples by ultra-high performance liquid chromatography (UHPLC) combined with fluorescence detection following their liquid-liquid extraction (LLE)
- Multi-residue analysis of vitamin B (B1, B2, B5, and B9), and vitamin E (α-tocopherol, β-tocopherol, α-tocotrienol, and β-tocotrienol) in grass and grain samples of four different wheat varieties by liquid chromatography-electrospray ionization/multistage mass spectrometry (LC-ESI-MS/MS)
- Separation and estimation of four tocopherols and four tocotrienols in pecan nut cultivar samples using non-aqueous reversed-phase high-performance liquid chromatography (NARP-HPLC) coupled with atmospheric pressure chemical ionization-tandem mass spectrometric (APCI-MS/MS) detection
- Analysis of different cold pressed oil samples to detect and quantify eight tocol- homologs using a chemometrically-assisted optimized high-performance liquid chromatography (HPLC) with fluorescence detection (FLD) based method
- Multi-residue determination of tocopherols in aromatic peanut oil (APO) and four refined vegetable oils using high-performance liquid chromatography with UV detection to detect adulteration
