Health Care Products Quality Control

GFA Production Xiamen Co., Ltd. is a company dedicated to the production of dietary supplements and has production lines for liquid, capsular and powdery preparations.

We always believe that “quality relies on the production”, and try to meet the market demand and people’s health expectations with high-quality products.

Materials: the quality of all products is determined by the design, while the quality goals of the product are achieved based on control of raw materials. Our raw materials include vitamins, minerals and plant extracts. We use unique authentication methods for different types of products.

Vitamins: most materials are identified by their characteristic IR spectra; each material has a unique infrared spectrum which is similar to human fingerprints; Fourier Transform Infrared Spectroscopy (FTIR) can be adopted to quickly identify the authenticity of raw materials.

中文名:维生素B1(盐酸硫胺) English Name: Vitamin B1(Thiamine hydrochloride)
拉丁名:Vitaminum B1 Name in Latin: Vitanimum B1
试样制备:KBr压片法 Specimen preparation: KBr pellet
备注:醋酸酯结晶后做红外线光谱图 Note: infrared spectrogram is drawn after crystallization of acetate

Minerals: with atomic absorption spectrophotometer (AAS), minerals can be rapidly identified by the absorption of specific wavelength by various metals.

Plant extracts: the identification of plant extracts is complicated, for the plant extract contains polysaccharides, fiber, starch, nutrients and active ingredients. We choose some of the important active ingredients for identification, using different intermolecular forces of active ingredients and thin layer chromatography (TLC) or high performance liquid chromatography (HPLC) to separate and identify active ingredients.

Equipment: all equipment used in the production are made from materials that conform to FDA regulations and can avoid adverse effects to products, so as to improve the quality of products from materials, design and usage and avoid foreseeable contaminations.

Environment: all products are manufactured in Class-D clean areas conforming to FDA requirements; we will invite professional inspection and testing organizations as Zhangzhou Institute for Drug Control (a governmental agency) for regular testing, so as to effectively control the cleanliness of the production areas and ensure the environmental factors will not impose adverse effects on the product quality.

Each batch of our products can be provided with the appropriate COA. Some items are tested by our company’s own laboratory, while the other items are tested by famous third-party testing organizations with relevant qualifications, such as SGS and BV.

All measures are for providing high-quality products to customers.
