Elemental analysis of biodiesel (FAME) according to EN and ASTM standard methods with HR array ICP-OES
5 Jan 2023In this application note, Analytik Jena demonstrates the capability of the ICP-OES to quantify sulfur and other elemental contents in biodiesel samples following ASTM D4951, EN 14538, and ISO 20424 (for sulfur) methods. This allows for an economic analysis covering all critical elemental parameters in one run.

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.
