Graphite Furnace Atomic Absorption Spectroscopy

“The only source of knowledge is experience” — Albert Einstein Flame atomic absorption spectroscopy is a well established and precise method for elemental analysis giving concentration results in mg/L (ppm) levels. However, better sensitivity is achievable using electro- thermal atomisation with a graphite furnace. Limitations of flame AAS Burner – nebuliser is a rather inefficient […]

Interferences in Atomic Absorption Spectroscopy

Interference is a phenomena that leads to changes in intensity of the analyte signal in spectroscopy. Interferences in atomic absorption spectroscopy fall into two basic categories, namely, non-spectral and spectral. Non-spectral interferences affect the formation of analyte items and spectral interferences result in higher light absorption due to presence of absorbing species other than the […]
