We are committed to offering personalized and consistent services to both new and existing customers.

Aikang Quanxin Analysis Department Testing Items:

1. Nuclear Magnetic Resonance Spectrometer Testing: 1H, 13C, 19F, 31P, and other one-dimensional spectra. The laboratory is routinely equipped with dimethyl sulfoxide-d6, chloroform-d, heavy water, and methanol-d4, and provides 5mm standard NMR test tubes.

2. Liquid Chromatography-Mass Spectrometry and Gas Chromatography-Mass Spectrometry Testing: Qualitative analysis of 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, and study of chemical reaction pathways and mechanisms; clinical drug concentration monitoring, establishment of new drug quality standards, and pharmacokinetic research.

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

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

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

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

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

Nanjing Aikang Quanxin Analysis and Testing Center, with its domestic analytical instruments and professional technical team, has become a trusted partner for many research institutions, universities, and enterprises. In the future, we will continue to uphold the spirit of innovation, constantly improve testing technology levels, and contribute more to the advancement of scientific research and social development.
