Three Numbers on a Certificate of Analysis That Predict Gel Performance
A COA carries a dozen figures and most do not predict gel pack behaviour. The three that do, the limits to set, and the one number suppliers leave off.
Your SAP Spec Says 400 g/g. Your Tap Water Says 210.
Why a 400 g/g SAP datasheet turns into a 210 g/g gel in your plant: the liquid used for the test, divalent ions, and a 30-minute check you can run in-house.
