Atomic Absorption Spectroscopy Analysis

Instrument Information:

The instrument used is a Perkin-Elmer 1100B Atomic Absorption Spectrophotometer. This instrument can be run with an air-acetylene flame, or also with a nitrous oxide-acetylene flame, depending on what is needed for the element being analyzed. There is also a graphite furnace available.

Element Information:

You must use a separate, element-specific lamp for each element that you need to analyze. We have lamps available for the following elements: Ag, Al, As, Au, Ba, Ca, Cd, Co, Cr, Cu, Fe, Ga, Hf, Hg, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Pd, Pt, Rb, Rh, Sb, Si, Sn, Sr, Ta, Te, Ti V, W, Zn, and Zr.

What Types of Samples Can Be Analyzed?

We can analyze any solids, liquids, or oils that are capable of being fully digested by concentrated acids. Concentrated acids commonly used to digest the samples are nitric acid, hydrochloric acid, sulfuric acid, and hydrofluoric acid. Samples dissolved in organic solvents can not be analyzed by flame-AA.

Samples that are oxygen or water sensitive can be weighed out in a dry nitrogen atmosphere in a glove box prior to digestion.

If your samples are very unstable, you should contact Carol Carter in advance, to schedule a time when they can be analyzed as soon as they are brought to the lab. This can be arranged with prior advanced notification.
