Chemical Raw Material Testing and Analysis

Nanjing Aikang Quanxin Analysis and Testing Center is equipped with domestically advanced high-resolution 400M nuclear magnetic resonance spectrometers, a full set of Agilent series instruments including liquid chromatography-mass spectrometry (LC-MS), gas chromatography-mass spectrometry (GC-MS), high-performance liquid chromatography (HPLC), gas chromatography (GC), and other large-scale analytical instruments. Here, we have a high-quality management team and an experienced technical team. Customer demand-oriented, we continuously provide effective solutions and consistent services using the latest industry standards and technical means.

Service Items:

1. Nuclear Magnetic Resonance (NMR) Spectroscopy Testing: 1H, 13C, 19F, 31P, and other one-dimensional spectra. The laboratory routinely stocks deuterated dimethyl sulfoxide (DMSO-d6), deuterated chloroform (CDCl3), heavy water (D2O), and deuterated methanol (CD3OD). Standard 5mm NMR test tubes are provided.

2. Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) Testing: Qualitative analysis for food safety, pesticide and veterinary drug residues, toxic and harmful substances, drug impurities, organic pollutants, and biological samples; monitoring of synthetic reaction processes, analysis of main and by-products and intermediates, study of chemical reaction pathways and mechanisms; clinical drug concentration monitoring, establishment of new drug quality standards, and pharmacokinetic research.

3. Gas Chromatography (GC) Testing: FID detector, percentage content determination by peak area normalization method; quantitative analysis by internal standard and external standard methods (requires customers to provide reference standards).

4. Liquid Chromatography (HPLC) Testing: DAD/UV detector, percentage content determination by peak area normalization method; quantitative analysis by internal standard and external standard methods (requires customers to provide reference standards).

5. Moisture Content Testing: Karl Fischer method for moisture content testing (aldehydes and ketones require one week advance booking).

6. Optical Rotation Testing: Automatic polarimeter for sample specific rotation and sugar content determination.

7. Melting Point Testing: Sample melting point testing, range from room temperature to 350 degrees Celsius.

Additional Special Condition Sample Note: Due to the diversity of testing samples, our laboratory may not be able to meet all special conditions. If your samples come with specified special conditions, we recommend contacting us in advance to confirm whether the testing conditions can be met.
