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.
