Analysis of Trace Elements in Volatile Substances by ICP-OES

Volatile organic solvents such as acetone, petrol, and naphtha present unique challenges in ICP-OES elemental analysis due to their low boiling points and high evaporation rates during nebulization. This application report demonstrates how laboratories can overcome these challenges using a cooled spray chamber in combination with ICP-OES. By maintaining sample temperatures as low as -20 °C during nebulization, the method minimizes plasma instability and enables accurate trace element detection without extensive sample dilution.

The study focuses on the elemental analysis of trace elements in acetone, showcasing detection limits for over 30 elements—including Ag, As, Hg, and Pb—at ultra-low concentrations. Calibration was performed using standards that were matched to the acetone matrix, and the method achieved excellent recovery rates and long-term stability over 2.5 hours. This approach ensures high sensitivity and precision, making it ideal for laboratories handling volatile matrices in petrochemical or industrial quality control settings.

Powered by the SPECTRO ARCOS ICP-OES system with Dual Side-on Plasma Observation, the solution offers enhanced sensitivity and interference-free measurements. The system’s advanced optics and software-controlled parameters support fast, reproducible results across a wide range of elements.

Key Benefits:
- Accurate trace element detection in volatile organic solvents without extensive dilution
- Stable plasma performance using cooled spray chamber technology
- High sensitivity and reproducibility for complex matrices
