Overview

The universal TAS-986 single beam atomic absorption spectrometer, as an important means of determining trace metal elements, has the advantages of high sensitivity, good accuracy, and fast analysis speed. It has been widely applied in various fields such as geology, metallurgy, materials, medicine, environment, and chemistry, and is now becoming a very important instrument analysis method.

Product Details

As a professional manufacturer of analytical instruments, Beijing Puxi General Company has been committed to the research and development of atomic absorption spectrometers for many years. In 1997, it launched the highly automated TAS-986 atomic absorption spectrophotometer in China, which uses fully Chinese Windows operating software. All controls of the instrument are completed by computers, greatly reducing the difficulty of operation for analysts, avoiding human errors, and ensuring high analytical accuracy. Received a gold award at the BCEIA Awards in 1997.

Universal TAS-986 Single Beam Atomic Absorption SpectrometerKey Features:
1. The structural design of an integrated flame atomizer and graphite furnace atomizer has achieved automatic switching between flames and graphite furnace atomizers
2. Domestic companies adopt advanced horizontal heating graphite furnace technology to ensure uniform temperature of graphite tubes, reducing chemical interference and memory effects
3. Adopting a rotating lamp frame with eight lamps, automatically selecting the position of each element's hollow cathode lamp
4. Automatically set * * height position and gas flow rate to ensure * * analysis conditions; Automatic wavelength scanning, peak searching, and spectral bandwidth replacement
5. The flame monitor can monitor flame changes at any time. In case of accidental flameout, the instrument will automatically shut down the acetylene flow and prompt an alarm
