Decagon AquaSorp Isotherm Generator

The Decagon AquaSorp Isotherm Generator is a new sorption analyser that delivers moisture sorption isotherms accurately and rapidly.

What Use is a Sorption Isotherm?

Isotherms are vital for understanding the moisture sorption properties of many foods and pharmaceutical excipients, drugs, and powders. These properties aid in determining initial formulation as well as the chemical stability of a finished product.

Why is it So Fast?

The Dynamic Dewpoint Isotherm (DDI) method measures the water activity of the sample directly, rather than relying on gravimetric equilibrium. This allows the instrument to deliver hundreds of data points with unparalleled isotherm resolution.

The AquaSorp's innovative approach to isotherm determination, paired with Decagon's established reputation for quality, make the AquaSorp an excellent choice for food and pharmaceutical research and development.

Reasons to Generate a Sorption Isotherm

A moisture sorption isotherm gives insight into how moisture in your product behaves and can answer questions like:

• I’ve added a lot of water to the dough without changing the water activity level. Now I get a sudden jump. Why?
• What conditions will lead to recrystalization?
• What’s the recipe for maximum shelf life?
• How will a recipe change affect the water activity of the product?
• Can I use a model to estimate water activity of various different recipes?
• Does this ingredient have the buffering capacity to maintain its water activity in a high humidity environment?
