Atomic Absorption (AA) Spectroscopy

A highly robust technique, furnace AAS is capable of analyzing low volume liquid samples. Ideal for labs handling complex matrices on a routine basis, it provides very efficient interference removal, resulting in sensitivity of several orders of magnitude higher than flame AAS, enabling trace elemental determination in the low μg L−1 range and lower for some elements

Preliminary studies on flow

2003/1/1Because of these benefits, the FI-VG-AAS technique has been applied to either the quartz tube atomizer or graphite furnace atomizer with in situ trapping preconcentration, . The FI-VG-ETAAS using in situ trapping of volatile species of analyte, combines the benefits of automation of FI-VG and high sensitivity of ETAAS.

Graphite Furnace Atomic Absorption Spectrometry

Graphite furnace (also known as an electrothermal atomizer or ETA) atomic absorption (AA) is generally considered an ultratrace and microtrace analytical technique with limits of detection (LODs) in the low picogram range, precision of a few percent (relative In

Atomic Absorption Spectrometry

Atoms are produced in two different ways using AAS: flame atomization (FAAS) and electrothermal atomization (ETAAS) (graphite furnace and a L′vov platform). Thus, the determination of potassium using an atomic absorption spectrophotometer requires a light source (wavelength for K = 766.5 nm) and an atomization source.

Determination of sodium and potassium contents in palm

Graphite furnace AAS (GF AAS) seems to be a good option for determination of Na and K contents in PBP as it has been extensively used to analyze metals in complex samples (Henrique Lyra et al. 2009; Lobo et al. 2011; Rodrigues et al. 2014).

10.4: Atomic Absorption Spectroscopy

A typical electrothermal atomizer, also known as a graphite furnace, consists of a cylindrical graphite tube approximately 1–3 cm in length and 3–8 mm in diameter. As shown in Figure 10.45, the graphite tube is housed in an sealed assembly that has optically transparent windows at each end.

Guidelines for Troubleshooting and Maintenance of AA Systems

Causes of Poor Furnace AA Precision Missed injection Bubble formation in syringe Dirty dispensing capillary Using non-Agilent graphite tubes Graphite components excessively worn – poor electrical contact Wrong dispensing height Poor optimization – esp. drying
