Electrochemical method mainly refers to cathodic protection, that is, the sacrifice of the anode and the protection of the cathode method, so that the metal to be protected as the cathode is protected, such as the underground pipeline or chemical equipment, can be used as an anode of a metal block together with the connection of the pass current to protect.
Atomic absorption, or atomic absorption spectrometry, is an analytical method based on the absorption intensity of the outer electrons of gaseous elementary atoms in the ultraviolet and visible ranges of the corresponding atomic **** vibration radiation lines to quantify the content of the element being measured, and it is a method of measuring the absorption of light radiation by specific gaseous atoms.
The difference between electrochemical and atomic absorption methods applied to trace element analyzers
Electrochemical method is simpler to operate than atomic absorption method, occupies less space, atomic absorption method must have a separate room for operation, occupies a large area, and the operation process is complicated. In the price of electrochemical trace element analyzers than atomic absorption method of trace element analyzers cheaper, of course, have the conditions of large hospitals can choose atomic absorption method of trace element analyzers.
The value of these two detection methods are within the detection range, the accuracy is very high, if the township hospitals, the use of electrochemical detection method of the instrument is good, Hailifu's biochemical trace analyzers is the use of electrochemical detection methods, and an instrument in addition to detecting the trace, but also detect biochemical projects, a machine is very suitable for dual-use it.
