Cold Vapor Atomic Absorption (CVAA)
Mercury contamination poses serious risks across pharmaceuticals, environmental samples, and industrial materials. At RJ Lee Group, we specialize in precise mercury detection using Cold Vapor Atomic Absorption (CVAA)—a technique renowned for its sensitivity and reliability. Whether you're investigating product integrity, environmental safety, or regulatory compliance, our CVAA services deliver trusted data to support informed decisions.
What is CVAA?
Cold Vapor Atomic Absorption (CVAA) is a specialized analytical technique used to detect trace levels of mercury. Unlike other elemental analysis methods, CVAA converts mercury into its vapor phase, allowing for highly sensitive detection without interference from other metals. This makes CVAA ideal for analyzing volatile mercury in complex matrices where traditional methods like ICP may fall short due to volatility and instability.


What Can You Do With CVAA?
RJ Lee Group has successfully applied CVAA in real-world scenarios, including identifying mercury in old gymnasium flooring and supporting forensic investigations into hazardous materials. CVAA enables:
- Environmental Monitoring: Assess mercury levels in water, soil, or air samples with high precision at ppb levels.
- Regulatory Compliance: This includes analysis aligned with NIOSH and OSHA methods for occupational exposure assessments, as well as EPA protocols for environmental discharge and waste characterization.
- Consumer Product Safety: Assess mercury levels in raw materials that would include gypsum, talc, kaolin and others.
