Microfluidic Devices for Moisture Analysis

What is the Best Measure of Moisture?

Microfluidic devices are currently employed for moisture analysis due to their: -

Small size

-

Low cost

-

Portability

-

High sensitivity

-

Rapid response time

These devices can be used to measure the moisture content of various materials, including:

• Food
• Pharmaceuticals
• Chemicals

The moisture content of a material can be expressed in several ways, including:

• Percent moisture content

• Water activity

• Relative humidity

The best measure of moisture depends on the specific application. For example, the percent moisture content is commonly used for determining the moisture content of food products, while water activity is used for measuring the moisture content of pharmaceuticals.
