Vitamin E Analysis Service

Online Inquiry

Vitamin E is also known as tocopherol. Tocopherol has a complex structure, many types of isomers, and its biological activity varies widely. It mainly includes α-tocopherol, β-tocopherol, γ-tocopherol, and δ-tocopherol, among which α-tocopherol, β-tocopherol, γ-tocopherol, δ-tocopherol has the highest biological activity. Tocopherol has the effects of promoting fertility, delaying aging, assisting in inhibiting tumors, and preventing diabetes complications and atherosclerosis. It also has anti-oxidation and anti-aging effects. It is usually considered separately in food science. The LC-MS technology combines the high-efficiency separation capabilities of high performance liquid chromatography with the high resolution and high sensitivity of mass spectrometry. The samples to be tested can be analyzed on the computer without derivatization, which can shorten the analysis time and improve the sensitivity and sensitivity of the analysis.

Creative Proteomics can provide a fast, sensitive and accurate high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) for the determination of Vitamin E in samples, which makes sample processing simple and easy, and the total analysis cycle can be shortened. The precision and recovery rate of the test can meet the actual detection requirements, and the detection limit is low, which can be used for daily monitoring of Vitamin E content.

Applications of Vitamin E Analysis

  • Antioxidant and anti-aging analysis and application of Vitamin E
  • Qualitative and quantitative analysis of Vitamin E isomers
  • Reveal the molecular mechanism of Vitamin E activity
  • Ensure the quality and safety of food nutritional additives
  • Nutrition and health product development

Advantages of Our Vitamin E Analysis Service

Use the first-class HPLC-MS/MS platform to detect the content of vitamin E with high precision

Comprehensive solutions and competitive prices

Analysis report with short analysis period and high sensitivity

Meet the needs of multi-vitamin type testing

Service Workflow

There is no need for derivatization in sample processing in our operating technical process. After the sample is pretreated, it is directly injected for analysis. One injection can complete the quantification of Vitamin E in the sample online, which improves the accuracy of the method and the analysis efficiency of the sample.
