Chemical Analysis and Testing Institution - Analysis and Testing Center

Nanjing Acon Analysis and Testing Center, located in the Chemical Industrial Park of Jiangbei New District, Nanjing, is a service window established by Jiangsu Acon Biomedical R&D Co., Ltd., providing analysis and testing technical services to the public. Since its establishment, the testing center has continuously developed and improved, adhering to industry-standard analytical testing laboratories and the operational philosophy of "impartial behavior, scientific methods, accurate data, and efficient service" to deliver professional and efficient technical services to all sectors of society.

Our testing center is currently equipped with advanced large-scale analytical instruments, including a domestic high-resolution 400M fully automated nuclear magnetic resonance spectrometer, Agilent LC-MS, GC-MS, high-performance liquid chromatography (HPLC), gas chromatography (GC), and more. Here, we have a highly qualified management team and an experienced technical team, committed to meeting customer needs by continuously updating industry standards and technical means to provide effective solutions and consistent services.

High-Performance Liquid Chromatography (HPLC: Agilent 1100-1260)
Widely used in synthetic chemistry, petrochemistry, life sciences, clinical chemistry, pharmaceutical research, environmental monitoring, food testing, and forensic testing. Suitable for the analysis of compounds with poor thermal stability, low volatility, and high molecular weight.
1. Imported Agilent equipment, equipped with a diode array detector, meets the testing needs for most synthetic and natural products.
2. The laboratory is stocked with various specifications and brands of imported HPLC columns, offering a wide range of options and broad applicability.
3. An automatic sampler with a capacity of up to hundreds of standards ensures strong sample processing capabilities and timely testing.
4. Highly experienced testing personnel can assist customers in developing and refining testing methods.

Specific Rotation: Yidian Wuguang
Polarimetry is a method that utilizes the optical rotation phenomenon when plane-polarized light passes through liquids or solutions containing optically active substances (such as compounds with asymmetric carbon atoms) to measure drugs or check their purity. It can also be used for content determination.
Mainly used for: drug identification, impurity testing, and content determination.
Specific rotation is an important physical constant of optically active substances, which can be used to distinguish drugs or check their purity, as well as to determine content. The optical rotation of a substance is not only related to its chemical structure but also depends on the concentration of the solution, the path length of the light, the temperature during measurement, and the wavelength of the polarized light.
Unless otherwise specified, this test follows the Chinese Pharmacopoeia 2020 Edition, Part IV-0621 testing standard.
