From April 17 to 19, 2024, sponsored by the Instrument Information Network, the 17th China Scientific Instrument Development Annual Conference (ACCSI 2024), co-organized by the Analytical Instrument Branch of the China Instrument and Instrument Society, Nanjing Product Quality Supervision and Inspection Institute, I Want to Test Network, and Jiangsu Analysis and Testing Association, was held at the Jiangsu Shishan International Conference Center. During the annual meeting, the East-West Analysis AA-7090 Atomic Absorption Spectrophotometer won the honor of being a good domestic instrument, adding luster to its outstanding performance in the field of scientific instruments.
Mr. Wu Yan, Marketing Director of East-West Analysis, took the stage to accept the award (fourth from the right)
AA-7090 Atomic Absorption Spectrophotometer Instrument Introduction
AA-7090 atomic absorption spectrophotometer is a fifth-generation atomic absorption spectrometer developed by East-West analysis. It is a scientific instrument development and cultivation project of the Capital Science and Technology Condition Platform. It has won the 2016 Scientific Instrument Industry Excellent New Product Award.
The AA-7090 atomic absorption spectrophotometer instrument inherits the good stability and low failure rate of previous products, and adds key technologies such as transverse heating graphite furnace technology, variable magnetic field strength AC Zeeman control technology, and longitudinal Zeeman buckle back.
In 2020, he participated in the sixth domestic instrument and equipment verification and evaluation project, which was well received by the expert group and the laboratory.
application field
Food heavy metal and trace element analysis, biomedical analysis, environmental testing, soil and fertilizer testing, etc.
Instrument features
Vertical exchange Zeeman and deuterium lamp two background correction methods, users can choose different background correction methods according to specific samples;
Adjustable magnetic field strength ensures sensitivity and accuracy.
8 lamp automatic lamp holder, equipped with automatic alignment function;
Coded lamp identification technology can identify both hollow cathode lamps and super lamps.
Super lamp power supply, while ensuring sensitivity, consumes less power and generates less heat.
The combustion head is automatically lifted and lowered;
The graphite furnace visual system allows the operator to observe the whole process of the sample from just being injected to atomization, and during this process, the desolvation, drying and ashing parameters of the sample can be correctly set, thus obtaining reproducible results.
