Frequently Asked Questions

As Follow is Some Frequently Questions People Asked

1.What are Vitamin Reference Standards, and why are they important?

Vitamin Reference Standards are high-purity, certified substances used as benchmarks in analytical testing. They serve as a known point of reference for HPLC, LC-MS, UV spectrophotometry, and other analytical techniques.
In pharmaceutical manufacturing, they ensure the correct identity, potency, and purity of active ingredients like Vitamin A, B-complex, C, D, E, and K.
For food and nutritional industries, they support labeling accuracy and regulatory compliance, helping companies meet standards set by USP, EP, and ISO.
Without reliable reference standards, test results can become inconsistent, leading to failed audits, product recalls, or regulatory penalties.

2. Which types of Vitamin Reference Standards does uHPLCs provide?

uHPLCs offers a comprehensive range of vitamin standards, covering all key categories required for pharmaceutical and food testing:

*Vitamin A Standards – Retinol, Retinyl Acetate, Retinyl Palmitate
*Vitamin B-complex Standards – B1 (Thiamine), B2 (Riboflavin), B3 (Niacin), B6 (Pyridoxine), B9 (Folic Acid), B12 (Cobalamin)
*Vitamin C Standards – Ascorbic Acid and its derivatives
*Vitamin D Standards – D2 (Ergocalciferol), D3 (Cholecalciferol)
*Vitamin E Standards – Tocopherols and Tocotrienols
*Vitamin K Standards – K1 (Phylloquinone), K2 (Menaquinones)

Each standard is accompanied by Certificate of Analysis (CoA) with purity, lot number, and traceability information.

3. What industries typically use Vitamin Reference Standards?

Vitamin reference standards are essential across multiple industries:

Pharmaceutical Manufacturers: For drug formulation, stability studies, and GMP-compliant quality control.
Nutritional Supplement Companies: To verify label claims for vitamin content and ensure regulatory compliance.

JP (Japanese Pharmacopoeia)

This ensures that they are suitable for use in regulated environments, including pharmaceutical product registration, regulatory audits, and international compliance. Each batch is supported with extensive documentation, including a detailed CoA, MSDS, and stability data.

5. How should Vitamin Reference Standards be stored and handled?

Proper storage and handling are critical to maintaining the integrity and purity of vitamin standards:

Temperature Control: Most vitamin standards should be stored at 2–8°C (refrigerated); sensitive vitamins like Vitamin A and D may require freezer storage (-20°C).
Protection from Light: Fat-soluble vitamins degrade quickly under UV exposure; store them in amber vials or foil wrapping.
Humidity Control: Vitamins such as Vitamin C are highly hygroscopic and must be kept in desiccators or moisture-controlled environments.
Handling: Use clean, calibrated tools to avoid contamination, and always reseal containers tightly after opening.

uHPLCs provides detailed storage instructions with each shipment to help clients preserve product quality.

6. What documentation comes with your Vitamin Reference Standards?
