Dynamic Vapor Sorption (DVS) Analyses | Moisture Sorption Analysis for Pharmaceuticals, Chemicals & More

At Seven Star Pharmaceutical Services, we specialize in Dynamic Vapor Sorption (DVS) analyses—a critical technique for evaluating how materials interact with moisture and other vapors. DVS analysis is essential for industries like pharmaceuticals, materials science, food safety, and chemical manufacturing, helping businesses understand moisture-related properties that impact product stability, formulation, and shelf life.

Advanced DVS Instrumentation for Superior Analysis

We utilize both the DVS Adventure and DVS Intrinsic vapor sorption instruments to provide tailored, high-quality moisture sorption analysis.

​

  • The DVS Adventure instrument is equipped to record light microscopy images during testing, allowing us to monitor material changes, such as deliquescence and particle agglomeration. This added visual capability provides deeper insights into how materials respond under varying humidity conditions.

  • The DVS Intrinsic instrument is equally adept at performing moisture sorption experiments, though it does not include light microscopy. It delivers precise and reliable sorption data, ensuring comprehensive results for your material's moisture interaction profile.

Key Benefits of DVS Analyses:

​​​​

  • Moisture Sorption Isotherms: Gain insights into how materials absorb or release moisture across various humidity levels, crucial for stability testing.

  • Sorption/Desorption Kinetics: Understand the rate at which materials interact with moisture, vital for optimizing packaging and storage conditions.

  • Hygroscopicity Testing: Assess a material’s moisture sensitivity and determine how it will react in specific environments.

  • Temperature and Humidity Control: Simulate real-world conditions to analyze moisture interaction under controlled temperature and humidity parameters.
