Overcoming interferences in challenging sample matrices using ICP-OES

Due to its detection performance and matrix tolerance, ICP-OES is a key technique applied for the monitoring of environmental contaminants.
One of the regulated methods in environmental analysis is EPA Method 6010D (SW-846). This method prescribes the use of inductively coupled plasma optical emission spectrometry (ICP-OES) instrumentation for the determination of target elements in groundwaters, industrial and organic wastes, soils, sludges, and sediments. With the complexity of such samples, significant spectral overlaps are possible and must be corrected for accurate results. In ICP-OES analysis, this is typically accomplished using inter element correction (IEC). Once identified, the Inter-Element Correction (IEC) function was used to calculate the interference correction factors based on concentration.
This presentation will highlight how straightforward method setup for ICP-OES analysis can be accomplished even for the most challenging sample types.
