SPECORD 50 PLUS UV-Vis spectrophotometer for palm oil quality assessment

25 Jun 2026

This application note from Analytik Jena demonstrates the use of the SPECORD 50 PLUS UV-Vis spectrophotometer for the quality assessment of palm oil across the production value chain.

Using UV/Vis spectroscopy, the method determines deterioration of bleachability index (DOBI) and carotene content according to ISO 17932, enabling rapid and reliable evaluation of oil quality during processing.

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.
