When does wet chemistry testing help?

Direct laboratory testing may be useful when actual product composition needs verification, ingredient variability is important, supplier information needs independent assessment, a specification depends on measured values, or an unexpected result is being investigated.

When can calculation-based analysis be useful?

Calculation may be suitable where reliable formulation information exists, ingredient data are available, and the purpose does not require direct measurement of every component.

Wet Chemistry vs Calculated Nutritional Analysis

The key difference is simple:

Wet chemistry measures selected characteristics of the submitted sample.

Calculation-based analysis derives values from formulation or ingredient information.

PBR's service catalogue documents both wet-chemistry and computational nutritional analysis approaches.

When Does Wet Chemistry Help?

Direct laboratory testing may be useful when:

actual product composition needs verification;
Ingredient variability is important.
Supplier information needs independent assessment.
A specification depends on measured values.
An unexpected result is being investigated.

When Can Calculation Be Useful?

Calculation may be suitable where:

Reliable formulation information exists.
Ingredient data are available.
The purpose does not require direct measurement of every component.

Common Mistake

Treating calculated values and measured product values as interchangeable.

They answer related but different questions.
