General description

α-Tocopherol is a form of fat-soluble vitamin E and shows anti-oxidant, anti-inflammatory, anti-cell proliferative, and anti-cancer properties. Often the result of poor nutrition or low absorption of dietary fat, its deficiency is monitored in patient serum samples by LC-MS/MS or HPLC.

Application

This Certified Spiking Solution® is suitable for use in a variety of testing applications from diagnostic testing of Vitamin E deficiency to quality control testing of tocopherol-based dietary supplements or pharmaceutical preparations by HPLC or LC-MS/MS.The certified reference solution (CRM) in solution can also be used as follows:
  • 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
  • High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) based combined analysis of retinol, α‐tocopherol, 25‐hydroxyvitamin D2, and 25‐hydroxyvitamin in plasma samples of cardiovascular patients

Features and Benefits

  • Fully characterized under ISO/IEC 17025 and ISO 17034 accreditation
  • Accompanied with a comprehensive Certificate of Analysis (CoA) with data on stability, homogeneity, accuracy of concentration, uncertainty, and traceability
  • Rigorously tested through real-time stability studies to ensure accuracy and shelf life
  • Gravimetrically prepared using qualified precision balances to ensure minimal uncertainty
  • Flame sealed under argon into ampoules for long-term shelf life
  • Offered in a convenient, DEA-exempt format to improve laboratory efficiency
