Industrial Minerals Testing
Clark Testing is an experienced analytical lab providing ASTM test methods for a wide range of Industrial Minerals Testing. Clark has a long history of providing analytical chemistry services for producers and manufacturers of industrial minerals. Our lab is operated under a rigorous ISO 17025 Quality Assurance Program which assures that testing meets our customer’s criteria for their application and industry specification.
Clark’s analytical chemistry laboratory is equipped with state of the art instruments to test and analyze a wide range of raw minerals. We routinely support testing for product validation and product comparison. In addition to chemical composition analysis we also provide particle characterization testing. Our particle characterization services provide particle size distribution, density, surface area, and porosimetry.
Clark provides ASTM sampling and sample preparation services either at mine sites or barge & rail transportation terminals. We have in-house sample prep capabilities with machining, grinding and polishing capabilities to ensure qualified test specimens are being analyzed.
Analysis most commonly include:
- Elemental analysis – As ,Fe, Mg, Al, etc.
- Elemental Oxides – Al2O3, SiO2, Fe2O3, etc.
- Pyritic Sulfur
- Anions – Chloride, Sulfate, Phosphate, Nitrate
- Carbon, Sulfur
- Free and Total Sulfur
- Crystalline Phase Identification
- Silicon Carbide
- Quantitative Organic Extraction
- Acidity, Alkalinity, pH
- Oxidation States of Iron, i.e. Forms of Iron
- Loss on Ignition, i.e. Change on Ignition
- Moisture Determination
- Particle Size Distribution
Clark Laboratories analytical chemistry lab is an ISO/IEC 17025 accredited laboratory providing testing services to all industries on an array of materials. Testing is driven by client need of benchmark testing, product comparison, product verification, and failure analysis.
Clark Testing’s Industrial Hygiene Laboratory supports Environmental Health and Safety (EH&S) programs for varying industries. accredited by the AIHA Laboratory Accreditation Programs (AIHA LAP, LLC), we assist customers in selecting the proper NIOSH or OSHA method(s) necessary to carry out the appropriate sampling.
Clark’s particle testing services, combined with our analytical chemistry testing, allow our customers to benefit from one resource for material analysis: both chemical and physical properties. We provide such testing services to industries including: Agriculture, Medical/Pharma, Food & Beverage, Electronics, Energy, Primary Metals, and Heavy Industry. Materials include: catalysts, aluminas, propellants, ceramics, filters, cements, adsorbents, activated carbon, carbon black, paints/coatings, medical implants, electronic components, cosmetics, nanotubes, and many more.
