AOAC 994.02: Determination of Pb in Edible Oils and Fats by GF-AAS
25 Sept 2014In this application note, the AOAC Official Method 994.02 for the quantitative analysis of Pb in edible oils and fats was performed using a Shimadzu AA-7000 Atomic Absorption Spectrophotometer. The advanced designs of the AA-7000, ASC-7000, and GFA-7000 all contribute to high accuracy, high precision, and high reliability.

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.
