DVS dynamic moisture adsorption analyzercharacteristic

The process of manually measuring adsorption isotherms is tedious and time-consuming. Traditional moisture adsorption analyzers are expensive, slow, and have limited data points to collect. The AquaLab VSA moisture adsorption analyzer is easy to operate and reasonably priced. The testing time is short, the amount of data collected is large, and hundreds of data points can be collected within 48 hours, making it more accurate in fitting isotherm equations.

DVS dynamic moisture adsorption analyzerIt is the earliest analyzer capable of generating Dynamic Dew point isotherms (DDI). AquaLab VSA can also set up Dynamic Vapor Adsorption (DVS) analysis, allowing the instrument to easily switch between two different analysis methods.

Using mirror condensation dew point technology, the speed is fast, and hundreds of data points can be collected within a few days. Random "comprehensive moisture analysis software" function *. Not only can it be used to generate water adsorption isotherms, predict the stable water activity of the product, but it can also be used to display the effect of changing the formula on the water activity of the product, and calculate the final water activity of the formula. And it can calculate packaging requirements for specific shelf lives.

High precision moisture adsorption isotherms can be obtained within two days, and hundreds of data points can be collected within 48 hours

Set indicators -

Set a water activity index that stabilizes the product. Predicting physical changes and biochemical reactions that affect product shelf life

Guiding formula -

Display the impact of ingredient or formula changes on the product

Highlight details -

Traditional isotherm data collection has limited data points. AquaLab VSA analyzer collects hundreds of data points within two days to measure shelf life stability -

Predicting the impact of harsh storage environments such as high temperature and humidity on shelf life

The curve obtained at a constant temperature, with the moisture content in the sample as the vertical axis and the water activity (relative humidity) as the horizontal axis, is the water adsorption isotherm. Studying the moisture adsorption characteristics of products has important guiding significance for the formulation, production, packaging, and storage of products.

For example:

Optimize product formula

A certain drug manufacturing enterprise hopes to plan the production of drugs that have just completed clinical trials. The water adsorption isotherm can be used to guide which formulation of raw materials and excipients can improve the stability of drugs. The water adsorption isotherm can also provide information about drugs under abnormal conditions such as high temperature and high humidity.
