Description

 

Equipment description:

Atomic emission spectroscopy is an analytical method in which the atoms of the element under test are excited by heat or electric energy and emit characteristic spectra.The instrument USES inductively coupled high frequency plasma torch as the atomic emission spectrum of excitation light source.It is mainly used for qualitative and quantitative analysis of elements in samples.

Basic principle:

Plasma excitation light source (ICP) is used to vaporize the sample, dissociate or decompose it into the atomic state. The atoms may be further ionized into the ionic state. Atoms and ions are excited in the light source.The light emitted from the light source is decomposed into a spectrum arranged by wavelength by means of a spectral instrument.The sample is qualitatively analyzed according to the measured spectral wavelength, and quantitatively analyzed according to the intensity of emission light.

Features:

• wide application range, capable of measuring more than 70 elements;The detection limit was low, and the aqueous solution could reach 0.1-1.0g /L.

• fast analysis speed and simultaneous determination of multiple elements;

• high accuracy, RSD<1% when element concentration is 100 times of its detection limit;

• good selectivity and inter-element interference;The linear range is wide, up to 6 orders of magnitude.
