Our 6-Step Quality Control Protocol

Batch consistency is maintained by executing testing checks at each step of the calcite and chemical carbonation process.

01

Raw Material Sourcing Purity

Limestone feedstock and calcite raw mineral are sourced from premium high-purity calcite quarries and verified for calcium carbonate assay and minimal acid-insoluble impurities before processing.

02

Reactor Carbonation Sizing

During precipitation, carbon dioxide gas and hydration ratios are monitored. This allows reactors to control the crystal habit (forming uniform aragonite patterns) and initial particle width.

03

Classification & Sieve Residue Checks

For both GCC and PCC, materials undergo automated air classification. We verify sieve residue (checking that 99.5% - 99.9% passes through a 325 mesh / 45 µm sieve) to prevent grit problems.

04

Microbial Testing (Pharma/Food Grades)

For KLC-101 grade, we test for total bacterial counts and yeast/mold parameters in clean lab rooms, enforcing standards under WHO-GMP and FSSC 22000 specifications.

05

Laser Particle Diffraction

We analyze d50 (medium diameter) and d97 top-cut using laser particle size analyzers. This ensures consistency and prevents formulation drift for plastics and coatings.

06

Retention Samples & Traceability

Every shipped batch is stamped with a unique batch serial number. We retain physical verification samples and laboratory test records for 12 months to ensure traceability.
