PAA-1800EL
TOP
The PAA-1800EL atomic absorption spectrometer is widely used in industries such as scientific research, quality inspection, disease control, environmental protection, metallurgy, agriculture, forestry, and chemical engineering. The innovative software and hardware design ensures the accuracy, safety, and ease of use of sample analysis, and the instrument maintenance is simple and convenient.
Integrated design
The graphite furnace power supply and atomic absorption host are located in one instrument, which 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.
Graphite furnace has high temperature control accuracy and fast heating speed
By using high-power transformers, micro resistance cables, and light controlled heating methods, combined with software and hardware temperature correction systems, the temperature control accuracy in the high temperature section can reach+1%. More safety protection measures are taken to make sample analysis safer and more reliable. The cooling water of the graphite furnace. Real-time flow monitoring and protection
Monitor the pressure of the carrier gas through a pressure sensor, and automatically control the flow rate of the carrier gas by monitoring the temperature of the graphite furnace through a photodiode. The internal and external gases of the graphite furnace are all automatically controlled by the computer according to the software heating process, using a 150 position rotary graphite furnace
Automatic sampler
Polar coordinate rotary graphite furnace automatic sampler, with high positioning accuracy, stable and reliable operation, and easy use and maintenance
