Atomic Absorption Spectroscopy: Key Parts

Description

Atomic absorption spectrophotometry uses a set of key parts to measure light absorbed by atoms. The main components are a radiation source, an atomizer, a monochromator, and a detector. Each part has a specific job in the instrument.

The radiation source is usually a hollow-cathode lamp, or HCL, ...

Transcript

An atomic absorption spectrophotometer consists of a radiation source, an atomizer, a monochromator, and a detector.

The radiation source usually has a narrow range, like a hollow-cathode lamp, or HCL, or an electrodeless-discharge lamp, or EDL. Instruments with continuum sources uses very high-resolution monochromators.
