Testing that Reaches the World
Clark Laboratories | Trace Element Analysis
Analysis for Quality, Environmental Compliance, and Commercial Value
What is Trace Element Analysis?
Trace Element Analysis identifies and quantifies metals and inorganic constituents present at very low concentrations.
Common elements analyzed include:
- Mercury (Hg)
- Arsenic (As)
- Lead (Pb)
- Cadmium (Cd)
- Selenium (Se)
- Nickel (Ni)
- Vanadium (V)
- Chromium (Cr)
- Iron (Fe)
- Sodium (Na)
Why Trace Element Testing Matters
Trace elements can significantly impact:
Environmental Compliance
Many regulated metals contribute to:
- Air emissions
- Ash disposal requirements
- Water discharge permits
- Environmental reporting obligations
› Proximate Analysis Testing
Fuel quality analysis including moisture, ash, volatile matter, and fixed carbon.
──────────
› Sulfur Analysis Testing
Sulfur testing for emissions compliance and product specification verification.
──────────
› Ultimate Analysis Testing
Elemental analysis of carbon, hydrogen, nitrogen, sulfur, and oxygen.
──────────
› BTU & Calorific Value Testing
Measure energy content for fuel valuation and combustion performance.
Equipment Performance
Certain elements can:
- Accelerate corrosion
- Promote fouling
- Increase slagging
- Damage process equipment
Product Quality
For petroleum coke in particular, nickel and vanadium concentrations often influence:
- Commercial value
- Refinery process monitoring
- End-use suitability
