CD BioGlyco's Comprehensive and Custom Analysis service ensures accurate analysis, enabling the utilization of sodium alginate's diverse applications effectively in various fields, especially in Pharmaceutical Excipient. Sodium alginate is a linear polysaccharide sourced from brown seaweed, comprising β-(1–4)-linked d-mannuronic acid (M) and α-(1–4) linked l-guluronic acid (G) units, known as M and G blocks. Sodium alginate exists in homopolymeric M–M and G–G forms, or alternating M–G sequences, forming a viscous gum upon contact with water. Sodium alginate widely serves as a corrosion inhibitor and in controlled drug delivery. Sodium alginate nanoparticles are prevalent in brown algae cell walls. Its versatility extends to drug delivery and targeted administration, benefiting from physicochemical properties and biocompatibility. Sodium alginate effectively inhibits corrosion in steel. Its advantageous properties include biodegradability and mucoadhesiveness, facilitating site-specific targeting.
CD BioGlyco's comprehensive sodium alginate analysis service ensures the standards of quality and purity through a series of detailed tests. Our service includes identification tests, content assays, impurities tests, and specific tests to thoroughly evaluate sodium alginate samples.
We utilize advanced techniques such as Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR) spectroscopy. These methods allow us to identify characteristic molecular structures and verify the chemical composition of sodium alginate accurately.
We use spectrophotometric methods and colorimetric assays, precisely measuring the alginate content. These techniques provide reliable quantification, essential for product consistency and quality assurance.
To identify and quantify contaminants, we employ high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS). These methods offer high sensitivity and specificity, ensuring that the sodium alginate meets stringent purity standards.

Results: Besides pharmaceutical and biological analysis, some physical tests can be done as sodium alginate is a chemical material. In this study, authors performed some analyses for sodium alginate include strength testing, degradation analysis, and micro-deformation analysis using digital image correlation (µDIC). Strength testing involved conducting tensile tests on tube-shaped specimens to determine their elasticity. Degradation analysis was performed to assess the degradation of sodium alginate samples in an artificial urine environment, with the degradation time depending on the chemical composition of the material. Micro-deformation analysis using µDIC allowed for the observation of changes in the material structure at a micro level under external forces. These analysis methods provide valuable insights into the mechanical properties, degradation behavior, and structural characteristics of sodium alginate-based hydrogel materials.
