Analysis of elemental impurities in diesel by HR ICP-OES according to ASTM D7111-16
8 Dec 2025Typical challenges that are faced when analyzing organic samples such as diesel are plasma instability, signal fluctuation due to carbon deposition and matrix-based spectral interferences.
Analytik Jena demonstrates a simple routine analysis using ICP-OES according to ASTM D7771-16 that can detect trace impurities, including sulfur, in diesel with high accuracy and precision.

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.
