Chapter 1 DW-TY-9900 Inductively Coupled Plasma Atomic Emission
Spectrometer (ICP-AES) Overview
1.1 The Main Structure of ICP-AES
DW-TY-9900 Inductively Coupled Plasma Atomic Emission Spectrometer(ICP-AES) consists of
sampling system, spark source, dispersion system, control and detection system, and output
system.
1.2 Brief Description of the Main Working Principle of ICP-AES
ICP-AES is based on the characteristic radiation generated by the atoms or ions of the measured
element being excited in the light source. By judging the existence and intensity of this
characteristic radiation, qualitative and quantitative analysis of each element is carried out.
1.3 Application
As a large precision inorganic analytical instrument, DW-TY-9900 ICP Spectrometer is widely used
in
1. Steel and its alloys include carbon steel, cast iron, alloy steel, high purity steel, ferroalloy, etc.
2. Non-ferrous metals and their alloys include non-ferrous metals and their alloys, rare metals
and their alloys, precious metals, rare earth elements and their compounds.
3. Water quality samples such as drinking water, surface water, waste water, mineral water,
electroplating waste water.
4. Environmental samples include soil atmospheric dust, fly ash.
5. Mineral samples such as geological samples, ores and minerals.
6. Inorganic non-metallic materials.
7. Chemical products include chemical reagents, inorganic materials, cosmetics, oil(gasoline,
diesel, lubricating oil, C5 and other synthetic gasoline raw materials, oleic acid) petroleum
catalysts, urea solutions.
8. Food and drink.
9. Animal, plant and biochemical samples such as plants, Chinese medicine and animal tissues,
biochemical samples.
10. Nuclear industry products such as fuel, nuclear.
1.4 Instrument Composition and Working Principle
ICP inductively coupled plasma single-channel scanning spectrometer, is a multi-element analysis
of the sequence test measuring equipment. The instrument consists of scanning spectrometer,
radio frequency generator, the sample introduction system, photoelectric conversion, control
systems, data processing systems, and analysis software. Plasma is generated from the triple
concentric quartz tube in a torch. Argon is put into torch pipe in tangent direction, the upper part
of torch is coiled with copper loop(intercom cooling water). High-frequency generator generates
the high frequency current(40 MHz frequency around 1 KW power) through the coil, producing
around Alternating magnetic field, ionizing to produce a small amount of argon ion and electron,
in the magnetic field under the accelerated collisions with other neutral atoms, producing more
electronic and ions, in the form of eddy current, EDM reacts in the plasma formed under the
plasma torch( That is, plasma). The plasma temperature could be up to 10000 K or higher.
Aqueous solution measured by the formation of aerosol spray into the center of the quartz torch
