Basic Principles of Atomic Absorption and Atomic Emission ...

Flame and Plasma Emission Spectroscopy are based upon those particles that are electronically excited in the medium. The Functions of Flame and Plasma 1. To convert the constituents of liquid sample into the vapor state. 2. To decompose the constituents into atoms or simple molecules: M+ + e-(from flame) -> M + hn 3.

emission source are so impressive that virtually all other emission sources [such as the flame, microwave-induced plasma (MIP), direct current plasma (DCP), laser-induced plasma (LIP), and electrical discharge] have been relegated to specific, narrowly defined appli-cation niches. Indeed, even much of the application field

Inductively Coupled Plasma-Atomic Emission Spectroscopy

ICP-AES, or Inductively Coupled Plasma-Atomic Emission Spectroscopy (also known as ICP-OES, Optical Emission Spectroscopy), is a type of emission spectroscopy that is often used to detect the presence of trace metals in a sample. Through the use of the eponymous Inductively Couple Plasma, an ICP-AES produces excited ions and atoms

4.3 Components of an Inductively Coupled Plasma—Atomic Emission Spectrometry System (ICP-AES) 4.3.1 Overview: An ICP-AES system can be divided up into two basic parts; the inductively coupled plasma source and the atomic emission spectrometry detector. Figure 4.1 shows the common components of an ICP-AES system from the late 1980s to the 1990s.

The spectra are dispersed by a grating spectrometer, and the intensities of the emission lines are monitored by photosensitive devices.

Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

(flame or plasma) Light and heat energy from high intensity source (plasma) High energy (light and heat) promotes an electron to a higher energy level (excitation). Electron falls back and emits light at characteristic wavelength Light emission is proportional to elemental concentration - -- -High energy (light and heat) ejects electron

An emission spectrometer can be identical to an absorption system except that no external light source is used to excite the atoms. In flame emission spectroscopy, the electrons in the analyte atoms are excited by the thermal energy in the flame. Thus the sample is the source of photon emissions through
