Sawyer Environmental Chemistry Research Lab


Instruments - Analytical

Perkin-Elmer Graphite Furnace Atomic Absorption Spectrometer
Model 4100ZL

Composed of:

  • Electrodeless discharge lamps with external power supply
  • Hollow cathode lamps with internal power supply
  • AS 800 autosampler
  • WinLab software

Atomic-absorption (AA) spectroscopy uses the absorption of light to measure the concentration of gas-phase atoms. The analyte atoms or ions must be vaporized in a flame or graphite furnace to be analyzed. The element containing vapor is contained long enough for the absorption of light at an element specific wavelength to be read by the spectrometer.

Current Applications:
As, Al, Cu, Cr, Cd, Ni, Pb, Se, and Zn at ppb levels

Additional Elements:
Analyses of many other elements with available EDL or HCL lamps.

Sample matrices:

  • Water (drinking water, natural waters)
  • Soil/Sediment
  • Biological tissue
  • Agricultural products
  • Food products
