A GBC atomic absorption spectrometer (AAS), equipped with the Hyper-Pulse deuterium arc background correction system and a flame autosampler were used. The programmable automatic burner rotation option was installed.

FLAME ATOMIC ABSORPTION SPECTROPHOTOMETRY SW-846 is not intended to be an analytical training manual. Therefore, method procedures are written based on the assumption that they will be performed by analysts who are formally trained in at least the basic principles of chemical analysis and in the use of the subject technology.

GBC Scientific Equipment Application Notes – AAS 2 Introduction Silica or silicates are a major constituent of materials such as rocks, lavas, minerals, slags, refractories, ceramics, glasses, cements and ashes. The analysis of such samples by atomic absorption presents some problems, and steps must be taken to overcome these.

of an MP-AES is between that of a flame AA instrument and an ICP-OES. The price, detection limits, and improved dynamic range of MP-AES make it an excellent alternative for food analytical laboratories, compared to flame AA. In the future, we believe that many flame AA users will transition to microwave plasma

3.3 FAAS: Flame Atomic Absorption Spectrometer . 4.0 Interferences . 4.1 Chemical Interference . 4.1.1 Lack of dissociation of the molecules, or dissociation to a molecule that will not dissociate further at the flame temperature. This effect may be reduced by addition of lanthanum, or by using the higher-temperature nitrous oxide-acetylene flame.

GBC Scientific Equipment Application Notes – AAS 2 Introduction It is often difficult to obtain a high degree of analytical accuracy in theanalysis of silicates due to the high concentration acid digest usually required to dissolve the silicate. Therefore we present this

Atomic absorption spec-troscopy requires that the atoms be in their ground state. At high temperatures ionization may occur, reducing the number of ground state atoms and therefore reducing the absorbance. This especially occurs in the nitrous oxide-acetylene flame, and some of the more easily ionized elements include calcium, strontium and barium.
