DNA/RNA Drug Moisture Content Determination Service

DNA/RNA Drug Moisture Content Determination Service is a specialized analytical service that quantitatively measures the water content in nucleic acid drug samples through multiple analytical techniques. Its primary goal is to accurately assess the ratio of free water to bound water in order to reflect the physicochemical stability of the drug during production, storage, and application.

In the research and production of DNA and RNA drugs, moisture content is one of the key factors determining drug stability and quality consistency. Excessive moisture can accelerate the hydrolysis of the nucleotide backbone or chemical modification groups, leading to drug degradation, reduced shelf life, and decreased efficacy, while insufficient moisture may disrupt the structure of lyophilized powders, affecting reconstitution efficiency and bioactivity. Therefore, precise determination of moisture content is not only an essential step to ensure the safety and effectiveness of nucleic acid drugs but also a core quality control parameter for formulation development, process optimization, long-term storage, and regulatory compliance.

Karl Fischer Titration (KF)

A classical high-precision method for moisture determination, suitable for trace water detection with sensitivity reaching the ppm level.

Thermogravimetric Analysis (TGA)

Measures weight changes of the sample under heating to differentiate between free water and bound water, while also providing thermal stability evaluation.

Infrared Spectroscopy (IR)

Rapid quantification based on water absorption features at specific wavelengths, suitable for high-throughput screening and quality monitoring.

Gas Chromatography (GC)

Releases water under heating conditions followed by chromatographic detection, suitable for simultaneously monitoring water content and other volatile impurities.
