Atomic absorption spectrometer (six lamp position, flame method)

1、 Product Introduction:

CAAM-2024C 型Atomic absorption spectrometer (six lamp position, flame method)It is jointly developed by multiple industry experts in China and renowned professors from Tsinghua University. It mainly uses flame atomic absorption analysis method, and also has multiple functions such as flow injection hydride atomic absorption method and graphite furnace atomic absorption method. It is a physical and chemical analysis instrument with many functions and high cost-effectiveness. Professors Wu Tingzhao and Chen Lianyuan, who developed this instrument, are experts in the atomic absorption industry in China for many years and have experience in developing various types of instruments. They have combined their years of experience to improve the sensitivity of element testing in atomic absorption spectrometers to a new level. Their technology enables the sensitivity of flame atomic absorption to reach a high level, that is, 1 μ g/ml/Cu absorbance ≥ 0.3 (sensitivity<0.015 μ g/ml/1% A).

2、 Detection methods and detectable trace elements of atomic absorption spectrometer (for reference only):

Atomic absorption flame method (air acetylene) can detect elements up to PPM level.

Sodium (Na), potassium (K), magnesium (Mg), calcium (Ca), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), platinum (Pt), gold (Au), copper (Cu), silver (Ag), zinc (Zn), cadmium (Cd), lead (Pb), bismuth (Bi), lithium (Li), etc.

IIICAAM-2024C 型Atomic absorption spectrometer (six lamp position, flame method)Main Features

1. High performance lamp power supply: Equipped with high-performance dual cathode power supply, the instrument has a built-in high-performance element lamp (dual cathode element lamp) circuit to avoid unstable factors caused by the use of external current adapters.

2. When adjusting the combustion assistance ratio of the flame atomizer, the equipment's gas path box adopts a dual gas path control flow method, truly achieving flow control of gas and auxiliary gas. Due to the fact that many manufacturers only observe the flow rate of combustion assistance gas and rely solely on adjusting the gas flow rate, they cannot achieve true combustion assistance ratio regulation. Especially when making samples of organic components, the reliability of this aspect is highlighted. Some manufacturers can only reduce the output pressure of the auxiliary gas if they want to change the flow rate of the auxiliary gas, which brings a lot of unnecessary cumbersome processes to the operation.

3. The monochromator adopts a gap elimination screw sine mechanism for spectral separation, eliminating the phenomenon of backlash and return difference in the transmission mechanism, and achieving faster wavelength scanning speed.

4. Multiple slits are adopted, and special slits for high-temperature elements that can be used in the visible light region are specially added to avoid some elements that cannot be detected or the detection results are unreliable.

5. The control of the Element Lamp Lighthouse adopts dual synchronous wheel and dual synchronous belt technology to improve accuracy, ensure smooth, precise, and reliable operation.

6. Core key components:

1) Photomultiplier tube: Original Hamamatsu brand.

2) Grating: Developed by Changchun Institute of Optics and Fine Mechanics, Chinese Academy of Sciences
