This analysis measures the optical properties of whiteness, brightness, and yellowness in minerals such as kaolin, talc, barite, calcium carbonate, and silica, as well as other materials including papers and polymers.
It is essential for grade classification, particularly for applications in the ceramics, paint, plastics, paper, and refractory industries, where optical purity directly impacts commercial value.
Our results enable mineral producers to determine suitability against industrial specifications, optimize processing conditions, and ensure consistent product quality in compliance with international standards.
a. We document and verify all incoming samples to ensure traceability.
b. Samples undergo physical, chemical and radiation screening to assess texture, composition and compliance with regulations.
c. Accepted sample types include Rare Earth Carbonate (REC), stone, sand and soil.
a. Crushing & Milling – Reducing particle size for consistency.
b. Sieving & Homogenization – Ensuring uniform particle distribution.
c. Fusion & Digestion – Preparing the sample for instrumental analysis.
a. WD-XRF (Wavelength Dispersive X-ray Fluorescence): Determines elemental composition.
b. ICP-MS (Inductively Coupled Plasma Mass Spectrometry): Detects trace elements at ultra-low concentrations.
c. Micro-XRF (Micro X-ray Fluorescence): Provides high-resolution elemental imaging.
a. Concentration Measurement: REE values are quantified with precision.
b. Certificate of Analysis (CoA): Official documentation is issued for quality assurance.
