CAAM-2001 (EQ) multifunctional atomic absorption spectrometer

Main features:
The CAAM-2001 series multifunctional atomic absorption spectrometer was proposed by Professor Wu Tingzhao (the developer of China's first atomic absorption spectrometer) and specifically designed and developed by experts such as Professor Chen Lianyuan (the designer of Haiguang GGX-6 instrument and Zeeman Kuiper background atomic absorption spectrometer). It is a large-scale precision analytical instrument with high level.
1. High stability: The baseline stability of this type of atomic absorption spectrometer is ≤ 0.002A/30min. The baseline stability of an atomic absorption spectrometer is a basic indicator for evaluating an instrument, and it determines a series of operating states of the spectrometer, such as noise, sensitivity, repeatability, etc.
2. High sensitivity: This type of atomic absorption spectrometer has high sensitivity. The sensitivity of this type of atomic absorption spectrometer is (1 μ g/ml copper Cu absorbance ≥ 0.28Abs).
3. High energy: The lamp current of this type of atomic absorption spectrometer is controlled at 3mA-5mA, the spectral bandwidth is 0.2nm, and the negative high voltage is between 150V-350V to achieve full transmittance. This way, your hollow cathode lamp can be used for more than half of the time, greatly saving consumables and procurement costs.
4. USB interface: The atomic absorption spectrometer is equipped with a USB interface, which is suitable for various types of computers and supporting office equipment, reflecting the instrument's foresight and compatibility.
5. Multiple advanced technologies: Beijing Haotianhui Science and Trade Company has multiple advantages in the manufacturing of atomic absorption spectrometers, such as high-performance hollow cathode lamps, metal sheathed glass high-efficiency atomizers, hydride generators, etc. The application of high-performance hollow cathode lamps has advantages such as high emission intensity, high measurement sensitivity, low detection limit, good stability, and disappearance of interference from adjacent spectral lines. The invention, production, and application of metal sheathed glass high-efficiency atomizers have greatly improved the sensitivity, detection limit, and stability of atomic absorption spectrometers. The application of flow injection hydride generator in atomic absorption spectrometer has achieved high sensitivity and detection limit of hydride atomic absorption method, high measurement efficiency, and can partially replace atomic fluorescence spectrophotometer.
6. Advanced technology, stability, and durability: It can be turned on for testing immediately after getting off the car. For atomic absorption spectroscopy instruments, this stability is excellent among similar instruments.
7. Flow injection hydride generator: The atomic absorption spectrometer produced by our company, combined with the hydride generator produced by our company, constitutes advanced pneumatic automation technology (only one click is needed to automatically complete the entire process of injection, generation, reading, and cleaning).
8. The graphite furnace system and atomic absorption spectrometer host switch automatically: After switching between the graphite furnace system and atomic absorption spectrometer, it is very simple and fast to switch from the system to the sample, greatly saving analysis time and facilitating customer use.
9. Humanized information processing software. Led by Deng Bo, a theoretical expert in atomic absorption analysis in China and a professor at Tsinghua University, this type of atomic absorption spectrometer data processing software integrates new achievements in data processing at home and abroad, combined with practical experience in the field of atomic absorption spectroscopy in China, to provide highly reliable data processing results. The designed software operation is both convenient and fast, making it a masterpiece in atomic absorption spectrometer software.
