Trace metal analysis plays a critical role in environmental testing, pharmaceutical analysis, food quality control, mining, and industrial laboratories. Accurate detection of metallic elements requires analytical instruments with precise wavelength control, stable measurements, and efficient sample handling. An Atomic Absorption Spectrophotometer enables consistent analysis of metal concentrations across a wide range of sample types while reducing issues such as spectral overlap, inconsistent readings, and frequent calibration adjustments.
What is an Atomic Absorption Spectrophotometer?
An Atomic Absorption Spectrophotometer is an analytical instrument used to determine the concentration of metallic elements in liquid samples. The instrument measures the absorption of light by free atoms at element-specific wavelengths. During analysis, the sample is atomized using a flame or graphite furnace. A hollow cathode lamp emits a wavelength specific to the target element, and the absorbance level is measured to determine metal concentration.
An Atomic Absorbance Spectrophotometer is commonly used for the analysis of:
Lead
Cadmium
Copper
Zinc
Iron
Nickel
Mercury
Arsenic
These instruments support laboratories that require accurate elemental analysis for environmental, pharmaceutical, food, and industrial testing applications.
