Fast and robust assessment of water quality using ICP-OES
16 Aug 2024Even in small quantities, many elements can have toxic effects when present in drinking supplies or food chains. As such, monitoring the trace elemental composition of drinking, waste, and surface waters is vital in the maintenance of human, animal, and environmental health. Examine the suitability of the Thermo Scientific™ iCAP™ PRO Series ICP-OES for fast, sensitive and robust analysis of major and trace elements in various water samples, including drinking water, following the DIN EN ISO 11885:2009 requirements.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples.
