Determination of major and minor elements in HF-digested soil samples
26 Nov 2020The accurate elemental analysis of soil and rock samples can depend on reliable and reproducible sample preparation methods. If silicate-based minerals are likely to be present in the samples, laboratories must use hydrofluoric (HF) acid during sample preparation to ensure complete sample dissolution. Regulated methods, such as US EPA 3052, require the use of HF to achieve total sample decomposition.

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.
