Performance characteristics
host 1. Reflection achromatic optical system.
The tyre mirror is used instead of convex lens as the optical focusing equipment of the instrument, which solves the problem of different chromatic aberration of different elements and improves the efficiency of the optical system.
2. Type C-T monochromator.
1800 line/mm, 230 nm blazed wavelength grating light splitting system is adopted.
3. Eight element light tower.
The eight lamps are equipped with eight independent lamp power supplies. When the lamps work, they can be preheated by seven lamps, saving the time for lamp replacement and preheating, and making element measurement more rapid and convenient.
4. Automation design.
In addition to the main engine power switch, the functions of the instrument department are monitored and controlled by the computer.
5. USB2.0 communication mode.
USB2.0 communication interface is adopted in the industry, which improves communication speed and is compatible with new computer systems.
6. Background correction system.
It has deuterium lamp and self absorption background correction modes. When the background signal is 1A, the background deduction ability is more than 30 times.
7. The appearance adopts streamlined sheet metal process design, which is simple, fashionable and elegant
8. Independent intellectual property, fully functional and powerful analysis software.
The user-friendly operation interface makes your operation as easy as a palm. It can switch between Chinese and English Windows style software interfaces. It can run under Windows XP, Windows 7 and other operating systems. It can automatically conduct qualitative and quantitative analysis, automatically calculate element content, and automatically generate test reports.
1. Pure titanium atomizing chamber, pure titanium combustion head.
It can prevent acid gas corrosion and has a longer service life.
2. Glass atomizer.
Special glass atomizer is adopted, with high atomization efficiency and convenient maintenance and replacement.
3. The mass flow controller realizes acetylene flow control.
The mass flow controller controls the acetylene flow with an accuracy of 1ml/min, and dynamically monitors the flow. It is convenient and safe to use.
4. More safety protection measures make sample analysis more safe.
1) Acetylene leakage protection
2) Acetylene pressure monitoring
3) Air pressure monitoring
4) Combustion head status monitoring
5) Flame status monitoring
6) Water seal status monitoring 1. Graphite furnace power supply is built in.
The graphite furnace power supply and atomic absorption host are located in the same instrument, which makes the instrument space more compact, shortens the cable length, reduces the electromagnetic interference of the graphite furnace power supply to the outside world, and improves the heating efficiency of the graphite tube.
2. Graphite furnace has high temperature control precision and fast heating speed.
High power transformer, micro resistance cable and light controlled temperature rise mode are adopted, and the temperature control accuracy in the high temperature section can reach ± 1% with software and hardware temperature correction system.
3. More safety protection measures make sample analysis more safe.
1) Cooling water flow monitoring
2) Carrier gas pressure monitoring
3) Graphite tube temperature monitoring
4) Graphite furnace temperature monitoring
4. Automatic carrier gas flow control.
The internal and external gas parts of the graphite furnace are automatically controlled by the computer according to the software heating process. General purpose automatic sampler for 150 position rotary flame graphite furnace.
Polar coordinate rotary disk type automatic sampler has high positioning accuracy, stable operation and convenient use and maintenance. (AAS8000-M and AAS9000-M products are in manual injection mode and are not equipped with automatic sampler) host
