Changing calcium lactate suppliers: when to recalculate the weighed amount

Set up the comparison

State hydrate form, water content and the reporting basis for elemental calcium. Convert both certificates to the same basis before calculating the batch addition.

Measurements to record

Hydration state (Identification result). Check water of crystallisation together with the loss-on-drying method. Elemental content (mg/g as received). Specify the target element, digestion procedure and analytical method. Verify hydration state before converting from total salt mass. Record the sample ID and method revision for repeat testing.

Interpreting the results

If sediment appears, compare acidity, background ions and cooling conditions. Retain the deposit and run water and formulation controls separately.

What to record

• Hydrate form
• Elemental calcium
• Moisture basis
• Mass weighed
• Dissolution
