What is DVS?
Dynamic Vapor Sorption (DVS) is an analytical technique — also referred to as dynamic vapor sorption analysis — used to precisely measure the properties of materials as they absorb or adsorb water vapor (or other vapors).
DVS dynamically varies relative humidity at a constant temperature while measuring, in real time, the amount of moisture absorbed or desorbed by a sample. The technique is widely used across industries such as polymers, pharmaceuticals, food, and cosmetics, particularly for evaluating moisture sensitivity and designing appropriate drying and storage conditions.
A simple illustrative example is a dry powder absorbing water. This process is analyzed by varying the vapor concentration surrounding the sample in a controlled environment and measuring the resulting mass changes. While water vapor is the most commonly used, the technique can also be applied to a broad range of organic solvents.
DVS is a valuable technology in laboratories worldwide, used across a wide range of R&D sectors and applications — from polymorphism and compound stability studies to the analysis of bulk and surface sorption effects involving water and organic vapors. It is also an essential part of quality control analytical techniques for formulation, scale-up, production, and packaging.
How Does DVS Work?
Dynamic Vapor Sorption rapidly measures the uptake and loss of moisture or organic vapors by flowing a carrier gas over a sample (weighing between 1 mg and 4 g) at a specified relative humidity (or partial pressure).
The sample is suspended from the weighing device of an ultra-high-precision microbalance — a Surface Measurement Systems patented technology.
Capable of detecting mass changes of less than one part in ten million, DVS provides the exceptional long-term stability required to accurately perform vapor sorption analyses, which — depending on sample size and material — can take anywhere from a few minutes to several days to complete.
In practice, the key factor determining the sorption behavior of a material is the need to establish rapid sorption equilibrium. With DVS instruments, accurate sorption behavior can therefore be determined using very small sample sizes (typically 10 mg), minimizing the equilibration time required.
DVS instruments are fully automated through the purpose-built DVS Control Software package, which provides a flexible and user-friendly interface for setting up and running sorption and desorption experiments.
The DVS Data Analysis Suite also offers a powerful environment for rapid plotting and quantitative analysis of data.
