The American PE atomic absorption spectrometer has increased communication speed and is compatible with new computer systems

The characteristics of the American PE atomic absorption spectrometer determine its important position in geological and metallurgical analysis, which not only replaces many general wet chemical analysis, but also has the same status
as X-ray fluorescence analysis and even neutron activation analysis.
A positively charged inert gas obtains kinetic energy from the electric field and hits the cathode surface, as long as it can overcome the lattice energy on the metal surface, it can sputter atoms out of the lattice, thereby producing resonance lines
of the cathode substance.
Because the pressure in the lamp is very low and the pressure becomes widened and small, the resulting resonance line is a sharp line light source
.
At present, atomic absorption method is used to determine more than 70 elements in geological samples, and most of them can achieve sufficient sensitivity and good precision
.
Performance characteristics: 1.
Total reflection achromatic optical system, using tire mirror instead of convex lens as the optical focusing equipment of the instrument, effectively solves the problem of different chromatic aberration of different element focus and improves the efficiency of
the optical system.
2.
Monochromator, using 1800 lines/mm, shining wavelength 230nm grating spectroscopic system
.
3.
Eight-element lamp lighthouse, eight lamps are equipped with eight-way independent lamp power supply, one lamp work, more can be preheated by seven lamps, saving lamp change and preheating time, making element measurement more convenient and fast
.
4.
American PE atomic absorption spectrometer automatic design, except for the host power switch, all functions of the instrument are monitored and controlled
by computer.
5.
Communication mode, improve the communication speed, compatible with new computer systems
.
6.
Background correction system, with deuterium lamp and self-absorption two background correction modes, when the background signal is 1A, the background ability is more than
30 times.
7.
Perfect function, large performance analysis software, humanized operation interface, make your operation easy to handle, can switch between Chinese and English Windows style software interface, can run under Windows XP, Windows 7 and other operating systems, automatic qualitative and quantitative analysis, automatic calculation of element content, automatic generation of test reports
.
American PE atomic absorption spectrometer can be used to study the structure and chemical bonds of molecules, and can also be used as a method to characterize and identify chemical species, using the characteristic wavenumber of chemical bonds to identify the type of compound, and can be used for quantitative determination
.
For example, some functions of the concave grating in the concave grating spectrometer usually use grating to disperse parallel light lines spatially and collect dispersed optical signals, so that most of the monochromatic images of the incident slit are focused on the focal plane
