The following is a detailed explanation of the structural design of TAS-986 atomic absorption spectrophotometer:
1. Light source system
Multi element hollow cathode lamp turret: Adopting an eight lamp automatic switching turret design, the working conditions of each element hollow cathode lamp are pre optimized and set. This design allows for quick selection of light sources for different elements, improving analysis efficiency and flexibility. Users can automatically switch the corresponding light source according to the elements they need to measure, without the need for manual replacement, saving time and operation steps.
Deuterium lamp background correction device: equipped with deuterium lamp for background correction, it can effectively correct complex background interference and ensure the accuracy of measurement results. When using the deuterium lamp to fasten the background, the instrument will automatically switch to the half mirror device, further improving the effect of background correction.
TAS-986 Atomic Absorption Spectrophotometer Atomizer System
Integrated flame and graphite furnace atomizer: The unique structural design enables automatic switching between flame atomizer and graphite furnace atomizer. This innovative design allows users to flexibly choose the appropriate atomization method based on sample characteristics and experimental needs, expanding the application range of the instrument.
Horizontal heating graphite furnace technology: Advanced horizontal heating graphite furnace technology was adopted earlier in China, which makes the temperature of graphite tubes uniform and reduces chemical interference and memory effects, while also lowering the atomization temperature. This not only improves atomization efficiency, but also extends the service life of graphite tubes, thereby enhancing the accuracy of analysis.
Pyrolysis coated LVOV platform graphite tube: Using a special pyrolysis coated LVOV platform graphite tube, the atomization process is further optimized, enhancing the sample processing capability.
3. Spectral system
C-T type monochromator device for eliminating aberrations: This device can effectively eliminate aberrations and improve spectral resolution. With five selectable spectral bandwidths, users can choose the appropriate spectral bandwidth according to different analysis needs to achieve the best spectral line separation effect.
Wavelength scanning and peak searching function: It has automatic control of wavelength scanning and peak searching function, which can quickly and accurately find the absorption peak of the target element, simplifying the operation process.
TAS-986 Atomic Absorption Spectrophotometer Detection and Data Processing System
Photoelectric conversion and detection device: including components such as photomultiplier tubes, responsible for converting optical signals into electrical signals and detecting them. These high-performance detection components ensure high sensitivity and low noise levels in signal acquisition.
AAwin control software: With a simple and convenient software interface, it can automatically switch between flame atomizers and graphite furnace atomizers, automatically adjust optimized working parameters and analysis conditions. The software also provides two types of background clipping: self absorption clipping background and deuterium lamp clipping background, making the analysis results more accurate. In addition, it can display and save all measured signal curves and temperature curves within the integration time for users to access and print. Simultaneously supporting report summary display and printing functions for both single element and multi-element analysis, as well as exporting data in multiple formats.
5. TAS-986 Atomic Absorption Spectrophotometer Safety Protection System
Flame monitor: Use sensors to monitor changes in the flame at any time. When the flame goes out due to unexpected power outages or operational errors, the instrument will automatically turn off the acetylene gas and prompt an alarm.
Acetylene leakage alarm: Monitor the concentration of acetylene in the instrument and working environment at any time. Once the alert concentration is exceeded, an alarm will be triggered immediately, accompanied by an audible prompt.
Abnormal pressure monitor: When using air acetylene flame analysis, the air pressure monitor constantly monitors changes in air pressure. When an abnormal situation occurs, it automatically cuts off the acetylene gas and safely shuts off the engine.
Comprehensive graphite furnace protection measures: The instrument simultaneously monitors the protection air pressure, cooling water flow rate, and whether the graphite tube is broken. When any abnormal fluctuations occur, heating will be immediately stopped and an alarm will be triggered.
