Analysis of Whole Blood for Trace Lead (Pb) by Graphite Furnace AAS
7 Jan 2013Toxic effects from heavy metals have been characterized in medical literature for decades. The standard clinical procedure for the measurement of lead in blood is very simple and is based on the use of highly sensitive graphite furnace AAS instrumentation. This application note demonstrates the Buck 210VGP Atomic Absorption System with the Model 220 Graphite Furnace option can be used to determine lead contamination in whole blood samples.

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.

Hematology also encompasses haemostasis and coagulation, thrombophilia and hemophilia, plasma viscosity and ESR analysis, hemoglobinopathies, cell morphology and haematinic measurement.Graphite FurnaceHeavy MetalsBlood AnalysisThe analysis of blood is vital for many areas of life sciences and forensic investigations. Blood samples can be tested for a number of different reasons such as diagnosis, glucose levels, cholesterol and drug testing.
