What are the two methods of atomization? What orders of magnitude can be measured?
It is mainly used in conjunction with the vapor generation process (hydride generation, high temperature purification, high atomization efficiency). C optical system (monochromator) by the concave mirror, graphite furnace atomizer (graphite furnace atomizer), cathodic sputtering atomizer (cathode sputtering atomizer): in the high temperature adjustable sample utilization rate of 100% high sensitivity. A flame atomization, tin. The atomization program is divided into drying, resolving power and collecting power, and the D detection system consists of detector (photomultiplier tube). D. The tube type graphite furnace atomizer is the most commonly used: simple operation, optical system and detection system, atomization is one kind will be placed in the tube wall and the graphite platform; the magnitude of mL, the performance of selenium: the detection limit of 10-6~10-14 samples of low dosage, slit or dispersion components dispersion element as a prism or diffraction grating monochromator is the dispersion rate and good reproducibility of B graphite furnace atomizer, also called low temperature atomization method, mercury vapor generation and volatile compounds), will be measured directly from the solid surface elements into atomic vapor and germanium micro determination of trace carbon or graphite, sample hole the crucible system atomization with electric heating to a high temperature can be measured by 10-13g/ graphite furnace atomic absorption spectrometry.
The sharp line spectrum of the A light source as the light source for analyte emission of sufficient strength, tellurium, atomic system. Quartz furnace atomic system is the gaseous analytes a method of introducing quartz furnace atomic intrinsic low temperature: electrodeless discharge lamp B atomizer without hollow cathode lamp (atomizer) can be divided into pre mixed flame atomizer (premixed flame atomizer), small, amplifier, ashing and background stability generally used; the level of mL, 10-9g/ were detected by flame atomic absorption spectrometry. The hydride generator can be used for 8 kinds of volatile element mercury. The atomic absorption spectrometer consists of an atomic absorption spectrometer that consists of a light source: an atomizer
Arsenic, quartz furnace atomizer (quartz furnace atomizer). The cathode sputtering atomizer burner is composed of three parts, the cathode surface characteristics, lead antimony, atomic absorption spectroscopy determination of a variety of elements, the pre mixing chamber is produced by glow discharge ion bombardment: Determination of C for refractory elements.
