Enhanced Trace Element Detection for Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES) with Ultrasonic Nebulization - Technical Note

ICP-OES instruments can provide laboratories with rapid trace level detection (ppb and subppb) for most elements. However, more stringent regulatory requirements have lowered detection limits for difficult to detect elements such as arsenic. The coupling of an advanced radial-viewing ICP-OES instrument with an ultrasonic nebulizer (USN) can help lower detection limits by up to a factor of 7. This technical note will list the improvement of these limits for this particular ICP-OES instrument
